Just installed the new beta. Looks neat, really. The one thing that never worked properly for me is the switching of input languages --- if I activate that widget, I see "Hebrew (QWERTY)" and "Greek" (which I use for typing math & phys symbols), but "U.S." is never visible. (I suspect it's menu item number 0.)
I ended up installing this widget by @kovpas Current input source icon instead, which does the job fine.
What would also have been neat is, if I could edit what showed up in the Emoji picker (which in my case would be a bunch of mathematical operators like ÷∩∪∝∞∆∇∊≈≲≳≠≡⊕⊗ )
