I'd switch to Ultimate for this - the use case I have is programming related:
In a project I'm working on there are ~60 external dependencies. As I'm doing framework/language upgrades I'd like to be able to use a lens to search the issue trackers of only those repositories for specific terms to find out if deprecations/removals are handled or if there are open issues relating to a search term. Most are Github (90%) and a few are Gitlab (10%).
This could effectively be a really powerful documentation/code search as well, which I use Dash for right now.
A hard limit kind of sucks for this use case as some projects could have 100+ repos in the lens, but even if it was limited to only Github/Gitlab it would be really useful.
