Suggestion:
add a menu item to the context menu when selecting one or multiple notes in list view that opens a list of all existing tags. This would allow tagging one or multiple selected notes quickly without having to manually add tags.
Practically this could be achieved by chaning the current context-menu item “Remove Tag” to “Edit Tag” which then opens a list of existing tags that you can select for that note or deselect in order to delete.
Reason:
I often find myself writing quick notes during the day and don’t want to take time to also add tags in that moment. But I like to come back later and tag my untagged notes.
On the Mac I can drag and drop notes easily onto tags in the tags column but on the iPhone that is not possible and would be complicated. Adding tag selection to the context menu on iOS would be a great feature.
