The UI looks so similar to MacOS native apps, that I sometimes lose the Agenda Window under a stack of open windows, unless I see the gold “On the Agenda” icon in the top left corner or the gold “Add New Notes” icon in the top right.
Dealing with my astigmatism and being diagnosed with dyslexia and attention disorder would benefit from a obvious visual cue like other apps use of color like, Whatsapp, Telegram, Teams, Steam, VScode, and Weather.
I suggest adding the color to more UI elements for a starter, like: the bottom left icons, move the community icon to the bottom right and fill it with gold, add a gold fill to the sidebar bumpers, change the color of the category names, tint the scroll bar. You can use a light touch or go full tint.
Allow users to toggle it.
