So why you wouldn’t simply copy .ini files? Feature you’re talking about would be only an UI for editinig.ini file.
Should be enough if you’re interested in copying existing preset. And you could save many “presets” this way in cloud.
Adding such feature for brand new projects is extremely minor thing. It only saves you one editor restart during entire project’s lifetime.
If somebody would actually add it, it would be useful to expose all parameters which requires editor restart. Yeah, this way it could be quite useful.
BTW… SVN is the worst version control you could use in gamedev. The best thing about it you don’t have to pay for it.
Git is great for code, but not binary assets. And difficult to use for artists.
P4 is designed for any size of project, works awesome with small and huge projects. File locking is also essential while working on binary assets a lot. Basic usage is easy for everyone.
There’s also Plastic SCM, promising, but never used it.
