I don't have an actual link to post, but I'd like to start discussion about the interface. It looks like windows 98, and while I don't think it looks bad per se, it definitely puts a date on the game.
The trouble is that BlocklandLauncher will automatically "fix" the image files if you replace them to mod the UI. There are addons to stop this but they cause issues and often cause Blockland to crash on startup.
Contradicting what I just said, here's SuperLoad, but it requires a DLL injection. Not sure if you could have this done automatically when BL starts up, or modify the BL executable file itself to include this, but regardless here it is.
