Love the app but I hate the look and options of the bottom navigation bar. Am I missing something or isn't here no way to customize it currently?
Would love to be able to make it something like this...
That's the source code for Voyager. If you want to make any changes not supported in the UI, you could change the source, then rebuild the binary for your own device and upload it to your device.
The code, IIRC is based on https://ionic.io/ so changing the icons for the tabbar involve modifying the ionic tab-bar setting: https://ionicframework.com/docs/api/tab-bar.
