Software Manager should have a Ongoing Installation Cancel option

  Under review

I am new to Linux Mint. While exploring the Software Manager of Linux Mint, I found that there is no Cancel option of ongoing installation of a package. I searched for forum, and somewhere I found a suggestion of pressing alt+F4 to stop all ongoing transactions. But it threw me out of SM. I think this is not an efficient way of stopping a process. It would be better if there is any option to do it in a convenient way.
