Finish up Nav Panel Bridge

So I was able to finish building the Nav Panel Bridge. It was a bit difficult since I needed to fix a few things in the UI code, so that it could map the callbacks correctly. For some reason, Objective-C doesn’t have any syntax highlighting and it doesn’t check for errors at compile time, so you just end up with it breaking at runtime. I also forgot to add a UI element to rename the folder and the Vault is kinda slow to open. I also need to highlight the selected Item and add an animation for when the window extends.
