Digisalt SNES Tileeditor
This is basically a reimplementation of TileLayer Pro in Java which makes it possible to run the program on any modern operating system (as opposed to the original program which was Windows only).
The original idea was to develop it for DSNESDS. In the end it was more of a finger exercise for the vastly superior tileeditor developed for the IDE... Still though this version was finished and features all of the original programs features (I think) including tileset editing and palette editing.
So if you're a linux/Macos guy you might want to give it a try.RHDN Project PageRelevant Link:
