Sorry! You are right. I know nothing about engine making, so that's unusual for me... i hope you could do something about that, because that's confusing and unintuitive. Thanks for your reply! ..but i think about syntax highlight you can just take highlight.js and add it to code? tho idk, i didn't use it.. I edited my previous message, because i understood how rude i was..
apology accepted :) and I want to repeat that I appreciate your genuine interest in the engine and feedback!
I will look into highlight.js and similar libraries, but to elaborate a little bit: One point against it is that right now trash engine itself is quite lightweight and any extra library would significantly increase the file size - and the smaller libraries I tried were somewhat buggy. I was also considering replacing the code editor with a text/visual scripting hybrid solution. So spending time on a syntax highlighting when I might scrap it anyways seemed a bit pointless.
