[ENH] Add action Show Variable Entry

Tile has a new action called “Show Variable for Entry” which allows the manual entry of any text to be submitted with the defined Custom command (or similar)

I get the reasoning behind sticking with “Show X” nomenclature here, but will casually toss an alternative out at you, namely “Input Variable”.

I take it by “manual” you imply “free-form alphanumeric entry” and not, say, a pre-determined pick list of values.

Correct and agreed. Not sticky to the name, but when browsing through the long list of actions, just need it to be clear what happens when you tap a tile. Felt that “Show a dialog that allows entry of a variable” was too long :joy::joy: and Input Variable too vague as to be unclear what happens
