Comment 2 for bug 169999

I'm working on a UI mockup in glade....so at some point I'll
toss ye a screenie of what I'm thinking (keeping in mind
I've never worked on anu UI stuff outside of web interface
design, so it might be a while coming)

As for filetypes, I think the 'common' ones like PNG, JPEG,
GIF...maybe others....anything the library (whatever would
be used for this) supports....the more the merrier I think
(is there a reason I'm wrong in my assumptions here?). Some
things would require special attention. For example, the
binary transparency in GIF (how to handle alpha-gradients),
the lack of transparency in JPEG (how to handle alpha
anything) and such...

As far as feedback, I think it should work pretty much like
a 'Save As' dialog. This the sort of walk-thru I'm thinking of:

* User selects 'File -> Export' from the menu
* User chooses a filetype and a filename (details of this
need some thought)
* User clicks 'OK' or similarly labeled button
* File is then exported, or if the file already exists, the
user is prompted with the appropriate choices (either:
"overwrite it or select a new name" or "overwrite it or
cancel").
* If its a new file, behave in the same manner as if you are
just saving it (close the 'Export' dialog and go on with
your business).

While there is no real notification when the export is
performed here I guess, it is better than the current setup
which lets you click the 'export' button and has nothing
change in the screen that the user is looking at. With this
setup, at least the 'Export' dialog would close which would
give the user at least some indication that the task had
been completed.
