Additions:

• Added #import (namespace) magic (see wiki).
• Code can now be edited from search results, which updates the source files.
• There's now an auto-formatting command (Ctrl+F2/Meta+F2) by topherlicious.
• Object icons now show in resource tree (can be disabled in preferences).
• You can now set custom icons for anything seen in resource tree, including recent projects.

Improvements:

• Event headers are now shown on event declaration line, when possible.
• #args magic no longer collapses arguments if it's clear that there are non-magic arguments afterwards.
• Tabs now have a small context menu on right-click.
• Included files are now shown in resource tree.
• Recent projects list now has a "remove from recent projects" context menu for items.
• Recent projects list now styles missing projects differently and offers to remove them.
• Global lookup (Ctrl+T) is now case-insensitive.
• Global search now looks in GMS1 macros like it does in GMS1 itself (and there's an option not to).
• Enum fields now display their value in auto-completion when it's easy enough to deduce.
• Editor component now has several attributes (file-name, file-path, file-kind) in case you want to change editor styles based on context.
• Added "open here" to context menu items - can open included files as plain text in GMEdit.
• Auto-completion menu now pops up automatically when adding a period "." after "global" or enum name.

Fixes:

• An error is now shown when trying to save an object with duplicate event declarations.
• Tab titles with double quotes no longer cause oddities.
• Labelled the rest of async event types.
• Fixed empty GMX actions saving differently (no trailing newline) than those produced by GMS1 itself.

Have fun!
