Ability to color notes

It would really help if Joplin had the ability to color notes. Example like this:

Since Jopling automatically sorts the notes… I would like if it would keep the order I set them to but the way it is written that would be difficult. I think it is easier to get to the same functionality by enabling the possibility to color notes. So for example I would easily know that notes related to meeting are colored blue.

Otherwise program is fantastic lightyears ahead of OneNote
