Sometimes we can get stuck. Therefore, it is good to know that you can get help from others using the same software. AfterShot Pro has a small but dedicated community, that can offer assistance.
Corel maintains official support forums for all their products. It is needless to say that AfterShot Pro has a section on these forums, too. There are always many experts willing to give advice if you ask nicely. Notice, however, that no Corel developers or other employees visit these forums. They are strictly limited to user-to-user support.
You can find it here: http://forum.corel.com/EN/viewforum.php?f=93.
Bibble5 by Bibble Labs was AfterShot Pro's predecessor. The old support forums at http://support.bibblelabs.com/forums/index.php still hold valuable information that can be used for AfterShot Pro, but you'll have to wade through the filth left by spambots as the forums have been abandoned for quite sometime.
This is my customToolsUI.txt file. I'm greatly indebted to the help given in various threads on the support forum for nudging me in the right way while creating it. Thank you!
