Lumeira 1.4 is out
A shortcut reference, a compare mode that follows your arrow keys, and view actions on right-click.
Three things in this one.
Press ? and you get every shortcut on one panel, grouped by what it does. If you have changed a key in Settings, the panel shows your key, not ours.
Compare mode moves now. Press K and you get the current image and the next one side by side. The right pane is highlighted. Left and Right move that pane through the folder while the left one stays put. Press A to open a third pane, click any pane to make it the one that moves. Up to four. Before this, the panes were frozen and the arrow keys changed something you could not see, which was our mistake.
Right-click does more. Compare, histogram, magnifier, rotate, flip, and actual size are at the top of the context menu, with their shortcuts in the labels.
Also fixed: error messages clear themselves instead of sitting at the bottom of the window, opening an image from another folder while the app is running now shows it, and two folder-navigation shortcuts that had never fired now do. The full list is in the release notes.
