Dev Build 2148 is out now.
The largest change is in tab completion: Pressing tab a second time will go to the next completion, with shift+tab going to the previous one. It works a bit like Ctrl+N/Ctrl+P in vim. You can still press Ctrl+Space to replace the last completion and show the menu.
There’s also a reopen_last_file command, and a corresponding menu item for it in the File/Open Recent menu.
There has also been a bunch of other completion related tweaks, primarily to benefit SublimeCodeIntel, although they won’t all be enabled until Kronuz has a chance to get a new version out. SublimeCodeIntel should also no longer cause undo to be per-character.
