I'd like to see a built in blob/tar function in the pipeline tool. Just line the files up one after another, and ad an index with byte offsets at the start. Pretty much what Tar does.
Then add a blob parser to the API that loads the index and can hand over file stream handles for loading.
Conceivably, one could add encryption to the mix. It would have to be pretty trivial to be decoded at runtime, but it would serve as obfuscation. Making it hard to get at the assets unless you really really mean to.
Secondly, a minimum size for resizable windows would be handy.
( I am new to MG, and I apologize profusely if either of these suggestions are already implement or solved already. )
