this makes way more sense, since all framebuffers should be created by classes anyway so having the classes call a function of the handler is just a waste of lines of code and compute time

Now window positions/sizes can be saved/loaded from a config file. Also autosave can be enabled to automatically save to that file whenever a change is made.
Next up is adding the interface for a global load/save system for any window to use

This class makes it easier to create and update popups with a similar structure to tabpage and window classes.

This makes the classes more consistent

Now the decode operations actually use multi threading. This reduces the rendertimes by a lot. A lot of the stuttering is gone and the decode seems a lot more consistent

Next up is loading gui settings from the given filename.
Also in the near future there will be a general settings file that allows each window and each tab to store all values they want to, without any potential conflicts. Each window will have its own json obeject and can store/load arbitrary data in it. Each window only has access to its own values to prevent potential problems.

This is disabled by default since it is broken on linux

This provides an easy feature to reopen closed windows. This is only really useful, if the window can be closed but it doesn't hurt to always register windows by default.
