That icon feels soulless. I'd prefer to stay with the current one, at least with the current design of gitify.

Or maybe I just need to get used to it... I'm going to leave it simmering 🥘

But if we do it, we should join #873 #874 and #876 with this one. It doesn't make sense to have them in separate PRs imo

Simmer away 😉. I noticed that the octicons are much sharper.

Personal preference perhaps... I'm very much in favor of small, independent, isolated PRs to assist with review speed and keep the line changed to the smallest releasable, particularly with refactoring PRs

Right, but in this case you are introducing icons that don't play well with each other if not done on one go.

I feel like if we switch to these icons we also need to completely revamp our UI to properly mimick GitHub's UI. As is, I still think ours are perfectly fine. If we do do these UI changes, then I think the icon changes make total sense

In the interest of moving this forward, I've consolidated into a single PR #885
