Thanks for all suggestions!
I don't think that sorting by mentioned options is well solution, at least it is not for sorting by the
Into and the
From fields, because of same reason which I stated in the previous post. As I explained, there is just limited number of presets and much more different possibilities which you get by using the Into and/or the From fields. For example, there is a preset "Clear the Comment field", so if you sort presets by the destination field you would get that preset under the "C" letter. But what if someone wants to clear the Lyrics field and looks at the "L" letter - s/he cannot find it there and s/he could think that this script cannot clear such field, which is not true. If I need to alphabetically sort presets I think it is much better idea to sort them by the preset name or the description, because in that way you could get grouped them by action, not by some field.
Just for information, you already could sort presets by their names, just open Export/Import dialog box and click on the table header. However you cannot undo that action.
I was thinking to add several groups by default and to put all existing presets in those groups, with a possibility for users to create new/delete existing groups or move presets between them wherever they want in similar way as they could with the Magic Nodes groups. However, instead of MN groups, I want here to limit such possibility only to one nested level - I think it would be enough and don't want to complicate further with several levels in depth. So, only what I need is a suggestion about names of new groups and how to group existing presets, i.e. in which groups to put them all. I think something about 10 groups, each with 5-15 presets, would be a good measure.
By the way, if you just want to separate some favorite presets form another, or your custom made from predefined, you could use the Export/Import dialog box. You just need to remove all preset that you don't use everyday and leave those favorites. If you sometime want to use some preset which you previously removed, only you need is to import that particular preset back from the stored .ini file.
One more by the way, long time ago I was thinking about a possibility to add one new option to toggle display of particular preset into dropdown list in the Search toolbar and Edit /Presets menu, but dropped that idea and instead of that I added Toolbar option. This is also some kind of "favorites" because you could decide which presets you want to put into the toolbar.
Well, if you ask me, I really prefer that "favorite" idea, because it would be much easier for me just to add one new Favorite check box, then to create all new way to group presets
I will think further about that suggestion.
