Thank you @roymacdonald!
Yes i know about the addon and about PG.
As you said PG is Electron + calls to OF CommandLine. So it is not a good option for me.
I would like to run an OF app with a UI based on CEF/electron, as if it was ImGui or any other UI running on the application. I have been trying the addon (its a fork by @Echolaitoc which seems more up to date) but i get crashes on runtime.
I will keep trying and see how far in can get. It seems to me that CEF + OF could bring many benefits that other UIs can offer, like allowing you to write portable HTML, CSS...
Ah btw i didn't know about Zack's project. Really cool!! reminds me of an old project of mine called Mask
