Found this bug with the actual version:
-Right click an item -> Ignore updates:
Addon will be visible on Options->"Ignore Updates" list
-> Remove addon from the liste HERE at the options tab (do not use the context menu of the ignored addon at the "Installed" tab!)
The adodn will be removed from the ignore update list, but the context menu of the addon at the "Installed" tab is still showing "Unignore this item".
-> I'm not able to ignore it again this way until I restart Minion
And in addition:
Please show some icon or info at the "Installed" addons list if an addon is ignored (like a red X or something like that).
