Yes it will be also for views. The changes should appear in the svn trunk
tomorrow.

for me a const access is enough! (anyway better than static variables)

also const makes sense for me, because it should be possible to get 
further informations but not to change the space..

is there any schedule for publication the changed interface?

and maybe the same (space access) would be nice for view-selection too!?

thanks

Martin
