Test build for #12. The app's updater won't offer it; install it over the version you have, and your groups and settings stay as they are.
- Open on hover with StartAllBack. StartAllBack draws a taskbar of its own whose buttons no other program can see, so a group there is now told by the tooltip its button shows: rest the cursor on the group and its panel opens once the tooltip appears.
- Everything in 1.8.1: the taskbar is read the way it is drawn on screen, and on a taskbar the app does not know, groups are found by the name of their pinned shortcut.
