Re: [Therion] symbol-show-and-hide

How do I use a layout to hide altitude points attached to the cave walls?

This is easy :) symbol-show/hide point wall-altitude

How do I show 'fixed' station points and show their names, but hide all other station points and names?

Unfortunatelly, this is not yet possible, it is in the TODO list. It is not complicated to implement, so if you need it for some presentation, just let me know, I can create some snapshot with this feature possible. All that needs to be done is to export station name and flags to metapost and than handle this with metapost code. In this case - it would be just two "if"s. Regards, S.
