Describe the improvement

Title says it all, Maybe this could be a setting or just simply an adjustment to how notifications work, But if UniGetUI is already in the foreground aka is focused, Do not notify - useless information I am clearly in the midst of seeing with my own eyes;
For instance I should not see a notification for updates available after I JUST clicked the button and didn't minimize the window instead am just awaiting the results, I'd like there not to be a popup if I'm clearly seeing what it's already gonna annoy me by showing.

Also yes i know there are settings to turn off the notifications entirely but that's missing my point.

Describe how this improvement could help users

Less annoying.
