I think that can be helpful to add the possibility to select a Base-Key like 'Ctrl' or Ctrl+Alt and after this to run any application using the combination between the Base-Key + the number of the tab were the application is placed - 'e.g: 1' + the corresponding key of each application. Also this think to be possible all the time, not only when the MadAppLauncher is active on the screen, also when it is minimized.
For example: Let say that the Base-Key is set "Ctrl". The Notepad application is placed in the Tab1 on the Key "N". The "MadAppLauncher" is minimized and I press "Ctrl+1+N" or "Ctrl+N". After this keys-combination to run the Notepad application.
If the number of Tab will be used on the hot-key, then to run the application from the corresponding key and respectively tab. But if will not be used any Tab number in the hot-key-combination then the to run the application from the last selected Tab: in above example -> Ctrl+N to run Notepad if the Last-Selected-Tab will be "Tab 1". Thank you!
