It would be nice to be able to 'Insert' a preset. If I have 100 presets and I want to add a preset to #4, then I would have to copy/paste every preset down one slot which is very tedious and time consuming.
There's a fixed number of presets, so you can't insert or delete them. However, you could is click and drag preset 101 up to the space between presets #4 and #4. This will shift presets 4-100 down one space and move #101 to become the new #4.
I am on a mac. Usually, when selecting multiple items I hold the Shift key and press Down Arrow until the range is highlighted/selected. This doesn't seem to work on the editor. I can't seem to figure out how to select multiple presets so I can drag and drop.
