Hello Eduardo!
Thank you for your quick response, and for helping me!
1. The new version is tested normally and has been used in my project, which solves the problem in the project and helps me a lot. Thank you very much!
2. Regarding the value of "TabKey", my personal suggestion is that it should have "uniqueness (there should be no duplicate values)"
3. For example, the "Key" value in the "ToolBar or TabStrip" property page can not be filled, if filled, the filled "Key" value is not allowed to be repeated, as shown in the screenshot below.
Thank you very much!
