Hi, Timo!
Currently it's possible to add a tag to only one specific time unit at once. Now I use tags as follow:
1) I mark with "important" tag time units for some planned and not completed issues.
2) I use a status tag, e.g. "done", to understand which issues on my long list for a day are completed.
For both cases I need to mark each unit in series.
Probably it would be grate if we could select multiple units at once and apply the tag to all selected.
Please, could consider this.
