Run cells with selected tag

[LukaPitamic]

Hi, I love this extension!
I use it for running specific cells in the notebook (probably I'm not the only one).
The problem - I cannot do it fast with keyboard.
Now I'm:

• selecting tab in left sidebar
• click: "select all cells with this tag"
• click away to the notebook (set focus)
• press ctrl+enter to run it
  ...again and again

I wonder if it would be possible to simply add "RUN all cells with this tag" bellow "select all cells with this tag" in extension sidebar on the left. It would speed up UX so much!

Never the less, awesome job!!!
