can be used as simply or elaborately as you want (has just about every helpful feature you can think of).
definitely comparable to other notes software that you have to pay for.
can make your own skins.
can't adjust size of additional skins (but there are some skins that are bigger in size).
after trying PNotes you may think twice about paying for other notes software that don't really have more features than PNotes but just perhaps appearances that you may want to pay for.
