Dev Build 2118 is out now, with a few polish related changes. Notably, expanding folders on the side bar is now easier: you can click anywhere in the row, rather than only on the triangle button.
The behaviour of “Find Next Using Selection” (Ctrl+F3 / Command+Option+G) has changed a little: if the selection is empty, it’ll search by whole words, otherwise it’ll search for substrings. The previous behaviour was to use whatever the current whole word setting on the find panel was. Ctrl+D/Command+D has changed in a similar way.
