Over time, we have discontinued features that shouldn't be in the code.

More code makes it always difficult to modernize something, so lets try to remove something:

Dead features from my point of view that need to be cleaned in the code:
Specgenerator
PhotoshopExporter
Qt5
Multilanguage/Translation

Done:
FlowView

Just dump here what you think should be removed, and if we agree, create tasks out of it.
