This should be a nice low-hanging fruit to fix.
"AT-SPI D-Bus Bus"? (Hell of a name BTW - gj GNOME team!) I know what it does, but the average user couldn't even being to guess, especially with a name like that.
"GeoClue Demo agent"?
MATE HUD - what does that do? I mean, I know what a HUD is, but I have no way of knowing if I'd want it running at startup or not.
Also, FIVE "Indicator XYZ" entries?! Am I the only one who thinks that's excessive?
Rather than just file a ticket, I thought it might be good to see if the community can come up with decent one-liner descriptions for them. Half the ones that do have descriptions aren't really at all helpful anyway. The "Spice agent", for example, has a description that basically just says "an agent for Spice" (not literally that, but literally that meaningless). Techically still better than "No description", but not exactly great.
