Bug? B4A Tab not show the module

Excessive number of modules, probably over 10 (depending on the screen width) will not be visible and drop down arrow will not list the module.

Workaround for those have multiple modules and some not appearing. Click the "Quick Search" and type in Sub Process and all the modules will display and select the missing one from there. It will then be added to the tab and drop down menu.

This is by design. Up to 10 modules are opened when the project is loaded. You can see all modules in the Modules tab. Click Ctrl + E and you will see them.
