Preset Numbering and Location

i know that dragging and dropping presets has already been asked for. i still want that, but in addition i'd like to be able to have presets numbered. maybe a little gray number in the upper left of the preset thumbnail maybe?

also, when i've got dozens or more presets for a given filter and i'm working on one that's somewhere in the middle (or anywhere, really), and i'm altering that particular preset but i want to keep the original and just add the mod right after the original so that they're together, would be nice. so, another item in the list where 'add preset' is, named something like 'add preset right after highlighted preset' would be good. obviously that's a silly long name, but maybe 'add sequentially' or something like that would be helpful. this is particularly useful to me when testing a filter or modding a filter and then testing out new addtions next to older ones, like with my 'the monster' filter which now has over 500 presets and i'm still modding it. see my dilemma?
