I've tried to use the "Reload mods" button several times when using this mod. This doesn't seem to causes any changes at all, particularly noticable when editing graphics/sprites. I'd also suggest using the circular arrow you have as the thumbnail for this mod as a sprite-button for the "Reload mods" button instead of the caption, but perhaps with a tooltip for "Reload mods" instead. Thanks for any help in advance.

Unfortunately you have to restart the entire game to see changes done during the data/sprite load step. Reloading can only reload code changes, as far as I know.

If you can fix the caption/image suggestion, please make a pull request and I'll include it.
