Tabs in panels
Each panel its tabs; Ctrl+Shift+D splits, F6 goes to the next. Drag a tab along its row, to another panel, or to a panel's right edge for a new one. The session comes back at the next start.
Features
Fast
Folders are read on worker threads and only the rows in view are built. Every folder shown is measured all the way down, and watched: a change made by any program shows at once.
Find it
Ctrl+F filters the folder by a few letters, in order. Ctrl+Shift+F searches every folder below. The types' popup keeps files or folders alone, or some extensions.
GoTo
Ctrl+G: a path with its folders completed as you type (Tab completes), or a few letters of a recent folder, a bookmark or a place.
The command palette
Ctrl+Shift+P: every action of the program, found by a few letters, with its keys. The menus are searched by typing too.
Batch rename
F2 on several items: a pattern with numbers, dates and ids, a find and replace, the case, or the names from the clipboard, each new name shown before anything moves.
Undo
Ctrl+Z puts back a rename, a new folder or file, a copy, a move, the trash; Ctrl+Y does it again. What an undo removes goes to the trash, never away for good.
Drag and drop
Rows out to any program as files; files from anywhere onto a folder, a list, a tab or the sidebar. A move on one volume, a copy across volumes; Ctrl copies, Shift moves.
Your system's look
The icons are your desktop's icon theme (the shell's on Windows). The inspector (Space) shows a picture, a text or a folder beside the list.
