Hi, thank you for the kind words and the wishlist.
I've identified the bug with the bag filter and will get it fixed for the next version.
Changes to the material glossary will also be made. Ctrl + Left Click can also be done, Ctrl + Right Click would be an issue however as some browsers (Firefox at least) will put a context menu up on Ctrl + Right Click that will obscure the game window. I'm also planning on adding an auto refill upgrade for flasks.
