Photoshop Extension Workflow

HI,

I would like to build a panel for my photoshop workflow and I am new to the Adobe scripting. I would like to be sure I have understood properly the user guide. Is not for commercial project, I am a photographer and I simply would like a panel that speed up my workflow with some actions and scripts.

I tried to find tutorials on internet but there is really nothing that explain deeply this

The extension Builder is not working, it says on my mac that the installer should be updated... I am using VScode. 

• Is there an easy way to test the extension? I copy the new version into photoshop for every change but is a bit painful
• The panel windows size cannot be modified, what would be the wat to achieve this? 
• Can I create an action from the JSX (not a script)

in terms of process... I create the HTML/CSS as for a normal website,the manifest and I use the JS file to do link the buttons and logic. Then I link with the evalscript the JS to the JSX, and this is what photoshop uses right? 

Still I need to figure out eventually how to sign the extension etcc... but maybe I will finish the panel first 🙂

Thanks for any advice 🙂 Hopefully the panel will be quite straightforfard and not causing too much headache
