I talked with nautilus people and well, it seems that is not possible right now to add something like gloobus (coverflow there) but I think that with this new version is possible to add key bindings and toolbar buttons.
I would appreciate if any of you can help me with this, just bind space key to launch
where filename is the file selected in nautilus
and add a two toolbar buttons un for coverflow (gloobus <floder>) and one for preview (preview <filename>)
If you can work it out please!! tell me! it will be one of best improvments on the application!
Now I'm very focused on making preview a very good application, redesign plugins to make it very easy to build one (yes!! very easy!!!!!!!!) and then I'll port gloobus to gtk + cairo + gtkglext using the same new plugins!!
I'll post on how to make plugins in the blog when I have it well perfiled!
I Hope we can improve it a lot!
