Dev Build 2120
is out now, with some important changes.
Firstly, hot exit is now the default. This means that the normal quit key binding (OS X) or closing the last window (Windows and Linux) won't prompt to save changes, instead the application will just exit immediately and restore the changes the next time it's started. This behavior can be changed with the hot_exit global setting. I've also placed a poll in relation to this
Another significant change is that the OPEN FILES section of the side bar is hidden by default (although the setting is stored in your session, so you'll only see this on fresh installs). Along with this change, the side bar will only show when needed: if the open files are hidden, and no folders have been opened, then the sidebar will be tucked away.
Goto Anything now displays files in most recently used order, although keep in mind that ctrl+tab is a quicker way to switch between recently selected files.
Take a look at the change log for the full list of changes.
