I'm looking for some advice on how I've structured this template application for writing dockspace apps with viewport using bevy (intended for creating editor applications that require a viewport) - it's only about 200 lines of code and is well commented.
I'm firstly curious about performance - I'm rendering the camera output to texture and displaying it in an egui widget. How bad is the performance hit of doing this and are there ways I can optimise it or write the code in a different way?
Secondly, are there ways I can improve this template to make it a better starting point for applications? The way data has to be passed in to
TabViewer to then use in tabs seems clunky but I couldn't find a better way of doing it.
