I fly using Sky Demon a lot and for me it’s 99% perfect, but I would like to suggest one small improvement.
ILS and DME frequency’s for military airfields can be displayed by one touch on the respective map icon, but for civil airports no such icons are offered, and the information is contained on the approach plate which are not so readily accessed.
For example try to look up the frequencies for Le Touquet or Norwich compared with Marham !
