I'm wondering whether it could make sense to apply "semi-markers" automatically when the time dimension in the panel is defined. So after a command like: setobs 4 1990:1 --panel-time that might imply setting obs markers of the form "G1:1990-1" or something like that. (G for 'group' which I think we use in gretl for the cross-section dimension.) Of course only if no other markers are defined already. Sounds 'natural' to me -- I mean that would be the equivalent to the behavior when working with time-series.
