ModTrace looks really helpful for hitsound modding, always forget after adjusting hitsound what hitsound I've changed since there are so many. Will give it a try soon.
However, posting here since I notice a bug which I've notice for a while (since v1.x). When you put aibat in a folder with ! at the end like osu! for example, you can't open it. No error message popup. It's fine if the folder name is !osu through or o!su, but not when it's osu! Not sure if this applies to any other letter/number/symbol.
Not the biggest issue and easily fix by just putting in a folder without ! at end, but as you can see, osu! folder has ! at the end by default and since aibat is use with osu!, I naturally put aibat in osu!'s folder. This is why I didn't use aibat for my earlier mods, since I thought it didn't work until I randomly redownload sometime after, notice it opening, but when put in osu! doesn't. Didn't report this error since it may just affect me, who knows, but been a really long time and still happens.
Hopefully the fix is easy, good luck, always looking forward to new aibat features!
