We will be translating it and allowing you to swap languages. This is currently disabled as the (test) translations we have are all just Google Translate, and as you can image...are a bit pooh. We will be getting proper translations soon.
You can do your own I guess...if you really wanted to, the file isn't massive - but you'd have to keep a backup away from the installation folder, and you'd have to DIFF it to see what new ones you have to do each release. The format is pretty simple
"ID" , "English version", "IDE translated text", "Restrictions", "Comment"
All you need to do is copy and rename the English one, then put translated text into the "IDE translated text" bit. The first line of the file has the above descriptors.
The restrictions will let you know if there are things like character restrictions and so on, while the comment might help where and how it's used.
Currently there are 3880 lines of text to translate, and you could - in theory just slowly work your way through. But I stress again, if you do, keep a copy OUTSIDE the IDE installation folder - it'll get wiped on an update.
We have designed GMS2 to be fully translatable, and it can switch on the fly, but until we have another properly translated language, we probably won't enable the option.
(unless the community start to do translations, at which point we'll enable it anyway)
