I just wish the little icons in the top bar were persistent (perhaps grayed out when not checked) and you can toggle them on/off by the little icons - rather than going through the menu.
Keep the menu there of course so if you want more information about the settings, it's there - but the ability to toggle on/off based on the little icons would be a nice QoL change.

The UI team seems to love their sub menus. Often to the detriment of having difficulty finding things - and some of the options are hidden under pretty obscure sub menus.. One example is Battle Effect Settings - you would expect that to be in either "Filter" or Graphical settings... However it's under "Character" which to me seems very obscure.. I often have to hunt around for some of these rather obscure settings if I am looking for something specific that I know is there..
