This workflow toggles the visibility (Opens foreront or hides it in dock) and/or opens an app by its name if it is not running already.

To add new apps:

Step 1 - Add a "Hotkey" from the triggers menu, configure it to the shortuct you prefer and if it is to run on an specyfic app or globally.  Step 2 - Add "args and vars" from the utilities menu. Replace {query} in the "argument" text box with the EXACT NAME (including capitals and spacing) of the app you wish to open. Step 3 - Sequentially connect the modules you created with one another to the script, like in the example. Step 4 - thank me :)
