If you prefer, you can still have it show on the right.<br><br>Update 2024.7.9.1<br>- Removed colors.<br><br>Update 2024.7.4.2<br>- Added dynamic button color change based on active layers.<br><br>Update 2024.7.8.1<br>- Updated the way max layers are calculated.<br><br>Update 2023.10.4.8<br>- Found out Layer Counter wanted to hangout with the cool kids from the FUME block. I scolded him and told him he can't hangout with them. I then sent him to the corner and told him not to move again.<br><br>Update 2023.10.4.5<br>- Fixed no display issue.<br><br>Initial Release.<br>- Hope this helps those that need to know how many layers they are using.<br><br>";
