Tangram is a browser for your pinned tabs. What this means is that I can put all my frequently visited websites in an app and have the ability to view them all with great ease. Before I was signing into everything each time I needed to check it but now I just switch to my workspace that has tangram open. I use mine for email, discord, and matrix. As a tab hoarder it’s also quite nice in how it clears up many of my tabs.
Yeah, I use librewolf which does that. However I also like this because it’s a totally separate app so I can just swipe with three fingers between my workspaces to access it.
