save last directory for each type of usage

[jstein]

most people have directories for their osm data.
one for tracks one for fotos and so on.
Something like this:

osm
├── coast
├── fotos
├── josm
├── poi
├── prune
├── rectified
└── tracks

It would be very handy, if josm could save the last or the "default" diretory.
So if the user imports pictures he does not need to navigate through the HDD
