Image Composer Undo
Hack to have multiple Undo Levels in Image Composer: Set a registry entry thus: [HKEY_CURRENT_USER\Software\Microsoft\Microsoft Image Composer\Settings] "MaxUndoLevels"=dword:00000010 I had to actually create the entry, but YMMV. I was amazed that this worked. Why this is not a default or at least a configuration option is beyond me. Update: Another annoying issue: When you have windows Display Settings Scaling set to a size other than 100% you will find that the color picker does not work correctly. Mine was set to 150% and this drove me nuts for a while. The fix is to move the window to a display with scaling set to 100%.
