Right now package manager shows ST3 packages in ST4 even if not supported by ST4 version. Can you please add supported package version or ability to hide this unsupported packages from showing up in quick panel when trying to use install command? I actually think any uncompatible package should be hidden by default from ST4.
For example see on https://packagecontrol.io/
It shows supported ST version for every package.
In quick panel when installing from ST4 only package version is shown not ST version. This can lead to users installing wrong version of old plugin to new ST4 and might even break something.
Right now only way to properly install ST4 packages is to go to PackageControl.io website and check manually. Which defeats the purpose of quick install from package manager inside ST
