v0.9.6 of recent-items (a “GENERAL” Plugin library plug-in type) has been migrated from the experimental repository of @kku and released to the Isotammi currated collection of add-ons.
The README.md is also moved.
It is available in the 5.0, 5.1, 5.2 and 6.0 addon lists. As with all Isotammi addons, this addon is for Expert audience under the 5.2 (and newer) Addon Manager.
See the Installation section of the Isotammi Addon wiki article for information about installing from the Isotammi collection.
After installing, all Object Select dialogs will include an extra sublist at the top of the dialog. This feature has no user selectable options or other interface. It can be un-installed (or hidden) via the Plugin Manager.
A big “Thank you!” to Kari!
