general notes

[vladmandic]

very cool extension but need to make couple of notes:

• why run separate web server (flask) just to expose several apis to its own js code? webui already uses fastapi, you can register extra endpoints easily.
• installer in app.py is custom and prone to failures, but extensions framework already provides for installer features? why have custom installer?
• location of editor in scripts is strange as it requires a lot of scroll up/down. plus many users use much more narrow left pane and wide results pane. this should realistically be an extension, not a script (just like openpose is).
• given that ui is written in js, it doesn't have look&feel of webui. controls should be inplemented in gradio, only canvas with three.js should be js code.

Support for depth map like this would be nice too.
