Fishing rod rendering is still somehow connected to the block outline thickness. I don't know why it happens, but there doesn't seem to be a fix I can implement myself and the problem seems to be occurring to other people as well, therefore I believe it to be a client issue. It is annoying to me and my friends and a fix would be much appreciated.
The chat mod is done really well, there are only 2 things I miss. First is the removal of empty chat lines, that are often used on minigame servers to keep their messages more readable, but are annoying to some people especially because they end up taking a lot of space. The second thing is preventing separator lines overflow. I am talking about the lines that servers use to separate messages (e.g. -----). They are often not the correct length (which would be the width of the chat) and are therefore overflowing to the next chat line. This can be easily solved clientside.
Potion colorizer is a mod which allows you to change the color of potions. Speed and poison potions (for example) are of a similar color, if not looked at carefully. It is very nice to have the ability to make the potion of poison of a more vibrant green color and speed the same variant of blue. It's a useful and (probably) not that hard to implement mod, which is to my knowledge not present even in Badlion.
