The focusing is great but why only 2 states for each focus item?
You currently have “+” and “-” but you need a 3rd option which disables/ignores the focus item, so we don’t have to delete the focus item.
For example…
I add a focus for Tidal and another for MQA.
What if I want to see all Tidal albums irrespective of if the are MQA or not? Can’t do it. I need to delete the MQA item to see everything.
I realize I can create bookmarks to recall favorite combinations of focus items, but being able to disable a focus item (ie it acts as if it was deleted) would be even more convenient for the user because the user can just quickly toggle items (+, - or disabled) without the hassle of changing bookmarks or readding a focus item if they had to delete it (because it cant be disabled)
