• can save a preset in settings

• change save for apply (in settings).

• need a trash to delete them. in the selection menu.

• select preset. in side panel. over the layer selector

when saving a preset. ask for the name in a dialog. reuse loaded preset name as default name. that way you can overwrite a preset with your modification or create a new one.
