Thank you for your kind words.

Alt+[left-click tag in tag-panel] toggles tag

don't you like the Note tags panel?

The tag(s) [in tag-panel] gets a right-aligned *,

hm, could make troubles with RTL fonts, plus many people wouldn't like the extra column

which depends on the note selected in notes-panel.
(or perhaps different colored or bold font, or other customizable formatting settings, or colored tag-icon)

and that would mean the tag panel has to be redrawed every time the current note or a tag changes...

If any of this is possible by scripting, a brief hint on what's required would be much appreciated.

it would be far to complex to alter the tag panel via the scripting engine...
@Maboroshy, any ideas?

On further thought, I think a sort-active-tags to top, as I added to first post is the most appropriate action, and the only one required. This would break least with current visual formatting standard, and for usability I believe it would be superior to all other alternatives. Imo, so far..

This would also enable quick navigation through related tags of active notes.

EDIT:
It's a question if the tags should be moved, or duplicated to top. If duplicated, they would need to have some type of a marker in the full list, to see what is selected.

@njorder, could you provide a real life use case where note tag panel fails you, but a proposed changes prevails.

For now I can only imagine the quick review of the notes with the same tag as a selected one, without hand-picking tags from the middle of the tag list.

As for quick tagging, I a long time drag-n-drop fan. Tagging just can't be quicker than this.

@Maboroshy, From/to where do you drag-n-drop..?

I still don't get what's wrong for you with pressing the keyboard shortcut to add a tag to the current note...

@njorder, drag-n-drop was a subject of #166 which was about UI for tagging too. It was rejected after internal testing.

Me and @pbek are still puzzled and waiting for some real life use case to understand your request.

@Maboroshy I will respond appropriately, but may you please explain first the drag and drop, is this an inbuilt feature or I must activate by scripting? I can't see any drag&drop functionality active in my windows version.

I was talking about a previously proposed feature that was not implemented. There's no drag-n-drop support in QOwnNotes.

Some people prefer the drag-and-drop way, but I find it utterly useless if you have more than, say, 50 tags, even if you somehow manage to «prioritize» them. The tag script + (default) autocompletion is faster and unobtrusive. However, I understand the preference of mouse over keyboard actions, not to mention the "complexity" of dealing with scripts.
