list of todos for myself:

• this first commit uses a zipped version of the GUI that I built locally from a PR. I need to take care to use the version ends up getting merged to main (ideally a pre-built download that's contained in the Releases page)

• If there are any visual changes when the official release is out, screenshots might need to be updated

• Document failure modes (here's a screenshot for example):
  
  

• Include latest Headstage 64 0.4.0 firmware images

Can you please describe what caused the two errors that you show?

Depending on which and how I might be able to clarify the error text itself.

(also one of them seems to have a typo?)

Just for clarification, when I say "document failure modes", these are not instances of the GUI failing, they're instances of the user failing to select the correct options.

This happens if you try a rhs2116 headstage with firmware intended for hs64 (e.g. if a user selects the wrong port with two different devices connected)

---

This happens if you try using this on a computer where onix isn't plugged in :P not even sure this is worth mentioning

---

I also came across this, but it seems pretty straightforward already

---

I didn't try to see what happens if there is no headstage connected at all, but it seems like it would be a different error than the ones presented above.

Ok, thanks!
I need to check the first message at least. It should first check for device ID and then hw revision after.
Also, I need to spellfix recision to revision
