An option to minimize/omit Normalization and Activation layers

[caiuspetronius]

Is your feature request related to a problem? Please describe.
Large networks appear about 3x times larger than they should because of the omnipresent normalization and activation layers. One doesn't really need to see normalizations and activations represented by the same size blocks as more important layers, e.g. convolutions.

Describe the solution you'd like
Ideally, an option to fold them into a line of a given color for normalization and another color for activation juxtaposed to the bottom of the block that they follow.

Describe alternatives you've considered
An option of omitting them altogether would be another solution.
