Hello, I currently play around with the layer feature. Currently it is so, that each "select"ed map goes in its own layer, which is fine. In my data there are nested maps however. They get collated into one big layer. I don't know PDF specifics, but it would be very handy to have "nested" layers, i.e. submaps as separate layers in the main layer. If sublayersa re not possible, it would be cool to have an optional option at the export config command to instruct therion to not collate submaps into a bigger layer, but add each map as independent layer. Something like this: ---- therion source ---- map A A1 A2 endmap map B B1 endmap map A1 scrap1 endmap map A2 scrap2 endmap map B1 scrap3 endmap ------------------------ ----- PDF layer list ----- - A + A1 + A2 - B + B1 ---------------------------
