Clicking Plus (New Tab) and X (Close Tab) to, firstly, stop getting folder sizes

[AugerJ]

Hello. I have the option "Show Folder Sizes" on and some folders with lots of files in them.
When the folder sizes are still being calculated and
I click Plus (New Tab) — nothing happens (whereas the associated shortcut works fine),
I click the tab to close it (X close button or middle-click) — nothing happens (and the associated shortcut works in an interesting way:
the first strike — "getting folder sizes stopped",
and then the second strike closes the tab).

Is it possible to include "Stop getting folder sizes" in the said commands?

Thanks.

Makes sense to me. Next beta...
