Cancellation of custom resolution support feature

[LinuxUsersLinuxMint]

We continue to improve AdWMGUI and release new version updates to make it better and better every day, but we are canceling the custom resolution support feature we introduced in AdWMGUI version 1.8, and why? Users can already get the window size they want by turning on the resize feature for the window they want, so we have canceled the custom resolution support. As LinuxUsersLinuxMint, we wish you a good day.
