Mike, thanks for writing this terrific program, I just got it today and have added a slightly different look by using another set of icons. There’s nothing wrong with those you supply, I am just really used to another set and have been for some time now. They look very neat shrunk down from their usual 256x256 - 52x is perfectly ok - but what is the max size one can use without messing up the program or making it work too hard?
They are known as JyrikShiny, I use them in other software a lot, and I took the standard distro of them and simply shrunk them down. I had to copy the - and na gifs into the same new folder as it does not have equivalents of them. I shall see what I can do about making some that fit in with the JyrikShiny style.
It’s very easy to skin this thing, and I look forward to seeing if I can make some fully original sets over time too. I do some 3d work so I may go that route and render a whole new set once I get my bearings on all that.
