All my problems would be solved if instead of the 'toggle key' actions there were 'toggle key then auto release(when there is a letter key press/event to complete the keystroke)' actions so that the modifiers are auto released instead of having to repress the relevant remote button to release the toggle. 
This should also allow for combination keystrokes like the ones i can already perform with the default actions you sent me by pressing each remote button in turn and then entering a letter key press/action to complete the keystroke, but instead it would also release all modifier toggles.

Please let me know if you will consider adding these adaptations as it would be extremely useful!

Thanks alot,
