Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Implemented an editable TextContent widget; it's now possible to edit text options using the GUI. The widget supports moving the text entry-point using arrows and home/end, but there's no visual indicator or edit-point setting using the mouse.
