Implementing it in the website doesn't seem necessary.
Maybe a link in the header menu?
Extended functionality inside ST itself would be nice though.
PackagesUI has done some work on it already.
It gives you this nice list of installed/activated/inactive packages and provides links to each plugin's GitHub page.
It only does it for packages you already have installed.
Often you need this info before you decide to install something.
Perhaps an easier solution would be to improve the package manager plugin itself by adding more info to the Install Package dropdown:
- Installation count (overall/recent)
- When the latest update was committed
- Github link clickable
- Highlighting a plugin in the dropdown opens the plugins readme file in a temporary ST buffer
The last one should have an option to be toggled off in case people run into performance issues.
