Organize tags with folders#281

I massively use tags to identify many criteria :

• tags for universe (western, scifi, zombies, fantasy…)
• tags for regions where the games in played
• tags for special game caracteristics or style (cartoon, pixel art, 3D, isometric..)
• and so on

I use colors for differenciate them.
But it could be great if we could group some tags in “folders” that could be quickly open/close to display/hide tags
