Slow Quick Switch Project With Lots of Projects

Description of the bug

When I have navigated to more than 15-20 projects the quick switch project popup takes many seconds to appear when I hit the hotkey to pop it up. This makes this feature much less useful if I could navigate to the project faster manually. I can fix this by clearing the recent projects, but that is a real pain as I have to manually switch to the projects.

I did not really start to experience a problem with this until recently, but I am not sure exactly when this started to be a problem but it has been an annoyance for a number of months at least.

In addition larger code projects (millions of files) often take a few seconds to become responsive when I make the switch. I maintain 6 ish clones of my primary project as I am often working on many features at the same time and it is often handy to have the clones on different branches at the same time. I also tend to work on quite a few different repos, each their own project as part of my daily work flow. It would be amazing if we could improve the performance of managing a long projects list and switching projects. This is an incredibly important part of my regular workflow (jumping around between projects)

Steps to reproduce

Pull down a larger number of larger repos and setup projects for each one. Jump around a lot.

Notice that when you pop up the quick switch project window it can take up to 20 seconds to appear. Also notice that once you have switched it can take a few seconds for sublime to become responsive again.

Expected behavior

Instant switch... Sublime prides itself on performance, so much so that we can't get features like variable font support.

Actual behavior

Slow, and sluggish switch
