Panther compatibility has been added! To use the panther features, save the project and open it using panther. Panther can be downloaded from pantherprogramming.weebly.com. If you open in scratch, you will see a lot of obsolete blocks from the panther features. I have tested and confirmed that when running it in scratch, the program simply skips over these undefined blocks without affecting the program. As for the online version, I'm not so sure, so this might be download only from this version on. It took a lot of effort for me to add these features, so bear with any technical errors they might cause since I had to convert the format from .pt to .sb. I must say, the panther features are pretty cool, and I would recommend you try them out. For those who don't know what panther is, it's an expansion on Scratch with more blocks and custom block compatibility. ENJOY!!! EDIT: Has been bugfixed to, well, work. Panther script will have to be dragged into mains script when opened in panther to prevent obsolete block crashes. I'll work on fixing this inconvenience for V0.4.
