New beta is out, with the ability to open directories as projects, among some other fixes and tweaks.
The behaviour of tab when translateTabsToSpaces has been changed slightly, too: it now adds spaces up to the next tab stop (i.e., multiple of tabSize). If you'd rather tabSize spaces always be inserted, set useTabStops to be false. Setting it to false will also make backspace always delete a single character.
A new application option (Preferences/General Preferences), find.useSelectedText, has been added. It's false by default, but if set to true, the selected text will be copied into the find panel when Ctrl+F is pressed.
