I just wanted to share the method I use to actually be able to see all meshes, their logs and parameters in the new UX and to create new meshes.
IN ALL MY PROJECTS, I just create a new simulation and label it 'MESH VIEWING/CREATION ONLY’
There, I can select a geometry from the sim’s Geometry selection Parameter.
Then, I can select any mesh that exists for that geometry from the sim’s Mesh selection Parameter.
Then, I click on 'Use mesh as Domain’
And Voila, there is all the buried information you wanted 
And, you can create all your new meshes there without fear of messing with ANY simulations’ active parameters 
Just sayin, since it took me a while to come to terms with buried meshes in this manner, and I hope this is temporary 
If SimScale made this a standard sim in every new project, and got rid of all sim root tree items in THIS SIM ONLY, below this sims Mesh selection Parameter, it might be a usable compromise without going back to the separate meshing tree of previous UX
