I can't seem to launch the app from dev. Any ideas?

dev server running for the electron renderer process at:

  ➜  Local:   http://127.0.0.1:5173/
  ➜  Network: use --host to expose

start electron app...

Oh! My bad. Wrong conda environment! -.-

The red error message popup disappears after about 18 seconds. That feels long. The error message popup on the subject ID / session ID page disappears after about 6 seconds. That feels better. Can we change it to disappear after less time?

Even better, could we make the popup disappear after the error has been resolved in the immediate form validation? That is minor and should probably be a separate PR

Updated both. Thanks for suggesting this!

Beautiful! Thank you.
