Hi, I recently installed Ubuntu MATE 18.04, and did the updates.
I'm using Pluma 1.20.1 and I want to configure the plugin called "tag list" but when you right-click on "tag list" (in Edit > Preferences > Plugins tab), "Preferences" is greyed out, and does not respond to being clicked.
I do have the tag list plugin enabled.
The version of Pluma that I used with Ubuntu MATE 16.04 had a similar plugin called "snippets", which was configurable via a nice interface.
