Ok well,

I tested the new version

copied the old files for comparison

ran the thing

and yeah, it just work and produces identical files

Can I get my 128KB now ?

Click to expand...
No, I'm against that. If the limit forces people to actually read their AI-generated posts and make them somewhat concise, or clean up their code slop before posting it here, we should definitely leave it as it is. You and your script are living proof that this limitation is a good thing. ;-p

By the way, isn't that why you want the higher limit in the first place? It's not because it makes things more difficult for users who want to use your script. In fact, I can simply click on the file and select "Open with text editor" in my browser, which is easier than copying the entire script from a code block in a forum post.

It's about making it easier for you to post it here, isn't it? ;-)
