The concept we're aiming for is "Extension Store" - Core to be minimal,. and everything else to be an optional install, with an "app store" somewhere here, and making installing extensions easy.

Isn't it possible to open a branch for that? who decide what feature can be integrated in Phorge? Just a remark, Phrequent *is* the application for time tracking, even quite empty by now

Looks great. I implemented a rough and simple logging feature over Phrequent, your extension looks more precise. I would think its better to merge/replace Phrequent rather than adding more implementations, though

Time tracking is an interesting topic. At my company we addressed this by having a Herald WebHook hit our internal server whenever activity we're interested in tracking happens. Our internal server tracks these activities from multiple sources (not just Phab/Phorge) and users can go in to see all their activity linked up and input the approximate time spent on those activities.

I'd definitely love to see this later. I MIGHT be able to get to this later.

This looks pretty great! - I think T15030 is the general covering task for Extensions
