On GitHub, I often hit the button “Subscribe” on an Issue, Pull Request or Discussion that I’m interested in. There is a fairly hard-to-find page, https://github.com/notifications/subscriptions, which lists all such “subscriptions”. Filtering by “Manual” shows just those where I hit that button.

Some projects track feature requests or issues on other platforms, like Userjot (used by Tally.so), Canny.io (by Strapi), Discourse (e.g. by Bitwarden and Anytype). Those platforms will often also have their own individual “subscribe” buttons.

I’d be interested in a kind of aggregation platform for issues, bugs or feature requests, to get a quick overview, grouped by project, of outstanding topics (issues, feature requests) that I’m interested in.

Assuming that it is also possible to check for updates or changes on these issues (like listening to issue closed events), it could also give a unified place to occasionally check for updates on these issues at my own pace, without necessarily subscribing to them. It would be nice if it could show that there were X changes in project Y since your last check.

The latter would be a superset of my GitHub Notifications, focused on projects that I do not manage myself. If I had that, I might also avoid the “Subscribe” action on GitHub itself, since very often it pings me for useless “+1 me too!” comments.
