ad 1 . I agree, this is not straight forward.
Presets of the present type? Or presets of the present category? Or logical groups of categories e. g. Phaser+Flanger? Or all effect presets?
And from which location? Local Library overall? Or just MyProfiler? Or preset packs included?
I was picturing presets of the present effect.
So as I described in the first post: if the present effect is a Green Scream, when right clicking on the slot you’ll get an option to load Green Scream presets.
Alternatively you could simply have a “presets” context menu which gives a list of all presets, and a sub menu within that which gives you just the presets for the current effect...in this case Green Scream.
I haven’t put much thought into which location they come from, but I would be fine with all locations. Or even another sub menu which breaks it down even further but that might be overkill.
The main thrust is that I think presets should be available by right clicking on each Stomp or FX slot, rather than having to navigate to the preset folders in the left pane. How that might be implemented is certainly up for debate.
