Project management
    •    Create both Inform 7 projects and extensions*
    •    Author's name or preferred nom-de-plume remembered
    •    Projects are automatically managed as single bundles (OS X) or folders (Windows)
    •    Projects may be freely exchanged between OS X and Windows, with no need of conversion tools
    •    Legacy Inform 6 projects and library files also supported*
    •    Intermediate build files are discarded when projects are closed, making them small and easily emailed
    •    Downloaded or home-written extensions are automatically organised
    •    Each project is displayed in a single window
    •    Project windows divide into a left and right-hand panel, showing two aspects of the project in parallel text
    •    Resize whole window or slide the divider to choose the proportions of left or right
 
Source text
    •    The source text is a single narrative, divided by up to five levels of subheading: Volume, Part, Book, Chapter, Section
    •    Search source from an in-window gadget
    •    Source text is automatically syntax-coloured
    •    Fonts, styles and colour-schemes all configurable*
    •    Paragraph indentation automatically managed*
    •    Sections auto-numbered (if desired)*
    •    Source text auto-saves on each compilation
    •    Search and replace
    •    Spell-checking*
    •    Entire project can be rebuilt from source text alone, with loss only of testing details (skein and transcript) in case of disaster
 
Documentation
    •    Complete but concise documentation can be shown in either or both panels
    •    Search documentation from an in-window gadget
    •    Organised as 20 chapters, each subdivided into 10-20 short sections
    •    Clickable links navigate contents of whole book or individual chapters
    •    More than 100 detailed examples included, graded in complexity
    •    Alphabetical index of examples included
    •    Examples can be pasted into the source text with a single click
 
Application World Model Language
Compilation
    •    Single button ("Go") compiles and plays the project
    •    Another button ("Replay") recompiles and replays the last sequence of commands
    •    Problem messages arising in compilation are automatically brought into view
    •    Problems have explanatory messages, with examples of correct and incorrect usage
    •    Clickback icons jumps the Source panel to any text being quoted
    •    Console transcripts show actual output from underlying command-line tools
    •    Application monitors for unexpected behaviour from the underlying command-line tools, surviving any crashes
    •    When there's no problem, word count, room count and item count for the project are displayed, to give a sense of its developing extent
 
Game
    •    A successfully compiled game automatically begins playing in the right-hand panel
    •    Fully standards-compliant Z-machine interpretation, including screen effects, based on the code bases of Zoom (Mac OS X) or Windows Frotz (Windows)
    •    Lengthy scrollback
    •    Command recall using the up-arrow key
    •    Interminably looping or otherwise out-of-control games can be interrupted with a Stop button
    •    Games otherwise stopped automatically on each recompilation: never any need to type "quit"
 
Index
    •    Index for every project continuously built and maintained, with clickable cross-references
    •    Numerous clickable links into relevant documentation sections, or to relevant points in the source text
    •    Seven different index tabs provide for:
    •    Actions, rules applying to them and commands producing them;
    •    Contents of the source text, usage of extensions, and bibliographic data
    •    Kinds of things (and values), and what instances they have
    •    Phrasebook of phrases, nouns, verbs and adjectives meaningful in the project
    •    Rules of general play and governing activities
    •    Scenes, as a chronological map of the story-line
    •    World map of the spatial arrangement of rooms
 
Skein
    •    Every command typed into the game is remembered
    •    Commands threaded into a downward branching tree called the "Skein"
    •    Skein is graphically displayed in either or both panels
    •    Click any knot of the Skein to recompile and play through to any position is any of these past histories
    •    Annotate the Skein to mark key moments, and use a pull-down menu to navigate these
    •    Skein can be be edited down (to remove lines no longer needed), or locked against accidental change
    •    Knots can be added by hand at any point, thus inserting new commands in the middle of existing histories
 
Transcript
    •    Transcripts of the game's replies to these threads are continuously recorded
    •    "Bless" a transcript to mark it as correct, and all future transcripts will be compared against this one, with any discrepancies highlighted
 
Publishing
    •    Parallel debugging and release versions of project managed
    •    Sections of source text marked "not for release" are omitted from release versions
    •    Story files use standard Z-machine version 5 or 8 formats, with support for Glulx in progress
    •    Complete Library Card of bibliographic data maintained on each project
    •    Each project is assigned a unique ISBN-like ID number
    •    Story files wrapped into standard Blorb archives with bibliographic data and cover art included
    •    Support for feelies and other additional resources - booklets, sounds, movies - intended to be available to the final player
    •    Option to create EPS-format line art of the game's map
    •    Option to add an introductory booklet
    •    Map drawing is highly configurable, with 35 modifiable settings per room
    •    Option to translate winning lines in the Skein to generate a walkthrough solution file, with annotations and branches
    •    Option to build a website to showcase the finished work
