I'd like a feature to specify to CWL which apps should show the label/caption in their panel button and which ones should show only the icon. For example, browsers, email, steam, etc don't provide any meaningful information by displaying this text in their buttons, and it only serves to make their buttons waste a lot of space on the panel, whereas file manager windows, when multiple are open, would be impossible to distinguish from one another this way, and therefore benefit from having their buttons show this info. Of course, different users will prefer different setups, hence the ability to specify for each app. For an example of this, you can look at 7+ Taskbar Tweaker for Windows.
