First of all: thank you for making this much-needed tool!
Now a feature request: it would be awesome to have the option to automatically prefix imported resources to avoid naming conflicts. So for example, I could set the prefix to "myprefix_" so that if I have an object named oPlayer in the imported project, the imported object would be renamed "myprefix_oPlayer" on import to avoid conflicts with any object named oPlayer in the project I'm importing into.
I realize this has the potential to break script code, but seems like it would still be a nice option to have. If you wanted to be ambitious, you could also have an option to do automatic search and replace of resources names in any imported scripts... so all references to "oPlayer" in code would be replaced with "myprefix_oPlayer" if I choose the prefix option.
Anyway, just a thought, but I think it's quite typical to have certain common objects share names from project to project, so a feature like this would take your tool to the next level, imo.
