You know what’s super duper annoying - when you select favorites in the wavetable browser and double click on a wavetable and then open the browser again it doesn’t show the favorites but all wavetables. The browser remembers all other folder selections, but not favorites, which is the most important one.
Yes, I “could” press the preset name, the “X” or the Esc key.
But: I simply expect all browsers in the plugin to behave in the same way (consistently), and not have to treat each one differently or react differently (as you do with the wavetables, for example).
