hi sudgy. thank you for getting the bundle!
hmm, this is really weird. i just checked the code and did a clean test on my end, and everything loads perfectly.
i attached a gif showing the exact steps. please take a look at it.
just a quick note: make sure you are adding them in the BRUSHES tab, not the DITHERS tab.
what exactly happens when you click Add file... and select the pack? do you get any error messages on the screen?
also, as a test, could you try installing v0.9.5 (it is available on the download page)? that version is from before the recent refactoring and has the original logic.
if it still doesn't work, could you please record a quick gif or video of your screen? seeing your process will help me understand what goes wrong ᨐฅ
