Hi Marcus,
regarding 2) In Pharo 3.0 one can already open a file browser on the
memory file system:
|fs|
fs := FileSystem memory.
(fs / 'hello.txt') writeStreamDo: [:s| s nextPutAll: 'Exported data' ].
FileList openOn: fs root
but it looks like it needs some love. One can create new files but most
functionality will not work. Should we create an issue?
Thx
