Thanks for the suggestions.
2) We are working on the Windows algo store at the moment.
3) Changing the name of the presets is under the More menu when a particular preset is selected, but I like your suggestion of double clicking on a preset to rename it.
4) We did intend to make that a feature but it hasn't made it in yet. It certainly would make reordering presets easier.
5 & 6) We're working on it…
