To use Fleet you have to download the JetBrains Toolbox. Really? Look, I'm a JB subscriber and have the toolbox, but Fleet should not require another app to launch or update itself.
[JetBrains employee] In the future Fleet will be able to update itself. Right now, we use Toolbox App as it can do Fleet updates easier.
I personally love Toolbox in our corporate environment. I just wish it would default to using system proxy settings on Windows and propagate Proxy settings to the IDE's it installs by default.
And a better way to handle certs for it, and all the IDEs, behind a corporate MITM SSL proxy would really improve my day.
