How about adding a close box after opening the add-in?
Opened in tab of excel file and now can't get rid of the window. Removed the add-in and now it give "Trust" prompt which when clicked reinstalls the add-in. So far acting more like virus than add-in

This is so annoying. WHERE IS THE CLOSE BUTTON?!
After battling with Excel for Mac I clicked on this daemonic add-in. OMG. I have a slow connection and nothing happened so I clicked again and now I have 2 screens over the top offering me nothing I actually want. How do I close them? I have looked for some obvious button but nothing. I tried clicking again and now I have another one. They are spawning!!!! Like some needy person you don't want or like that won't take the bloody message. It appears and won't go away. All I wanted was 2 legends the same style but being MS you have this built in frustration mode to randomise the look of anything.
Same here - so annoying!
