OK fine. The overruling startup in dusk mode with Standard layers I did as a simple if [iENC] then in te config reading of these values in the navutil.cpp. This could be ammended with hiding a few buttons (AIS hide btn force to all, hide scale up/down btn's, hide create route
btn, hide tides and currents btn's, hide route
manager btn, and hide tracking btn.)
At writing the config the above values should not be written to file. (So the 'original' values remain in the configfile)
At checking or unchecking the checkbox a reread of the configfile should be done. (for an instant adoption of new settings).
above could be done by me.
Add button(s) for direct switch to standard.
Add/change keyboard shortcuts for above.
Check if inland-standard is the same set of layers as sea-standard.
Am I forgetting something?
