It is good to have customizable workspace. I like how it done in Blender.
You can split window in any number of viewports and choose the desired content for each of them.
For example, it would be very convenient to have a node tree nearby to the final result (not just litle preview), like that:
Yes! Configurable viewports are definitely in LTE. As of right now, you can split the main view into up to 4 panes each of which can be set to whatever view you like. I haven’t settled yet on how best to expose viewport management in the UI - its likely to change between the first LTE release and the following ones, but it has very high priority.
As an example the new Blender UI has a lot to like - I like how they have things laid out.
