The ability to use the app in Chromium and embedded Chrome browsers.

So I am fairly sure that this would be impossible but as usual I thought I would put it out there just as an idea (I guess for those normal people not using Linux, the desktop app will make this irrelevant!):

I sometimes use browsers in embedded configurations, things like Electron wrappers or in the current instance Ferdium which is a Workspace OS type tool. Although these are running Chromium under the hood as far as I know, they don't have access to any of the extensions. Hence, while the UIs are very familiar, I greatly miss my favourite productivity tool and have to resort to the awful experience of using a keyboard (how did we ever survive?)

Maybe there's some work around or if not hope the Linux app comes to fruition one day!
