Press the PrtScr (or PrntScr) button on your keyboard. It stands for "Print Screen". Then just open up paint, and press Ctrl + V. This will paste it into the program. Then just save the file and send it to my email address [email protected]
Perhaps its time for you to build in an option to submit feedback/bugs so you can ensure you get all of the information you need to help with troubleshooting issues. Might also be a good time to add in a little Donate button in the app for your efforts as this is a great tool.
I just downloaded this and I'm loving it so far but I have found one issue that I can't seem to solve. I'm trying to redo the various rail textures, but I can't seem to find the "activated" versions of the gold rail and activator rail, so when I'm travelling on a track with my new textures, any time I pass over an activator or gold rail, it switches to the default textures.
