I like to remove some of my app shortcuts from default opening types, such as some app I already removed like browsers (some Chinese browsers I downloaded when my Chrome had some issue in China) but still would show up when I click on a web shortcut (and it prevent me from selecting Chrome as my default browser). And some duplicated shortcuts like wifi assistance (when I want to open wifi setting it will show two of them). And some shortcuts I don't even think they are in the correct category like Taobao (a Chinese shopping app) would want to be open when I open a web link or a photo.
P.S., looks like Chinese app makers really mess up your Android system with tons of random default app shortcuts.
