UVtools never had a layer volume histogram. It only have for the issues when scaned

@sn4k3 I swear on my heart there was one 😄 but if you say so I must believe. Should I change the issue title to: [FEATURE REQUEST] Layers Mass histogram display then?

It can be a feature, but can explain why this feature would be a good to have?

I've noticed some surface artifacts on my prints, and tracked them to the sudden change in layer volume. Currently UVtool has a buttons to jump to highest and lowest mass layers in the print, but to find when this sudden change occur one has to manually cycle through all the layers. Also it would be a nice visual indicator for Dynamic Lift post-process tool.

@sn4k3 Another edge case that would be served nicely by the "mass histogram" display is "empty layer detection": mark in read where histogram hits zero in between non-zero values.

That's already in, when having empty layers you got a red line one that layer
