[Feature Request] Add description to tags

[Heiss]

Hey,

i am using your tool for some days now, so barely new.

I would like to see a description field for tags, which is shown when selecting such a tag, like labels in gitlab, so i nudge myself to choose the correct label. Such description should be optional. Currently you need to remember yourelf.

Could also be a preparation for team time tracking, when someone new comes to traggo and should track time with predefined tags from team.

I think this is a very straightforward feature, but if any questions still open, feel free.

Bye.
