Option to cancel the export action

Hi everyone,

Is there an option to cancel the export action?
While the action is running it shows this nice “Exporting...” info:

But I could not find a way to abort the action.

And if one made the mistake to choose export 1064 x instead of w it takes quite a while until the export action is done. Meanwile I cannot edit anything else.

Why not add a little (x) next to “Exporting...” to give a possibility to stop the action? This would be great!

Best, Sarah​​​​​
