This looks amazing! Thank you :) Is there a way to request more icons to be added or a way to add custom icons? This is the probably the one thing that stops me from replacing draw.io with this!
Glad you liked it! Hoping to add a request icon form in the app soon and custom icons down the line. In the mean time, feel free to email support[at]onemodel.app with the list and I will add them asap.
