Please mention in the help file the defaults for command line mode, and what do they mean.
I'm not sure if the other modes have defaults, but in Sync mode this means "readonly daylightsavings timestamps attributes".
It's especially confusing as the GUI phrases 2 of them in a negative manner ("ignore X").
I have no way to know if, say, "readonly" is compatible to the GUI or does it actually mean DO include read-only files. Maybe it should have been called "no-readonly" and "no-daylightsavings".
is being vastly improved in version 3, some early releases of which you can see here: https://portableapps.com/node/21902
The manual in particular is recommended as there have been a lot of changes to the commandline. I do see what you mean about having a mix of positive and negative names though and I will try and come up with something better, thanks!
Can you mention the defaults and whether those two are positive or negative in the command line?
on the command line they match up directly to the user interface, true effectively ticks the tick box in the gui.
