[Shotwell] Ignore some files, existing tags

[dergringo]

Hello everybody!

Now that Shotwell supports hierarchical tags I love it. Thanks for all
your effort and energy. This is an outstanding application!

Well, there are two things I am not able to solve:

1) I would like to import .jpg and .jpeg files only and I don't want
shotwell to import my PNG's and my RAW's and stuff. How do I set such
a filter?
2) A friend of mine likes to over-tag his pictures and he adds a bunch
of tags to them. Now when he shares the pictures with me and I import
them to shotwell all his tags get added to my list of tags. How do you
avoid this?


Thanks and cheers!
