Dear Maintainers,
      When using the applications tab, it lists all applications on the
system. This takes quite a while to load when you have many
applications. On my system, it takes around 20 seconds to load the
applications tab, which mean 20 seconds of frozen computer time. What I
would suggest is to only load the first ~40-60 icons from the
application list, and then load the rest on demand while the user
scrolls down the list.
