When adjusting permissions for a category, it should show what channels are synced.

When you adjust the permissions for a category on a server, it should show what channels in that category are currently synced with the category's default permissions, and what channels have individual permissions, instead of having to go into each channel's settings to check if they're synced. Additionally, there could be a button to sync the channels with the category's permissions right there. This would make adjusting permissions on a server so much easier.
