Can I open multiple embroidery files and edit them at the same time?

When I sew an embroidery pattern design exported as DST format in PE-DESIGN, how do I specify whether or not the jump stitches are cut on the embroidery machine of the Innov-is series?

Why can't I import some embroidery files correctly?

I got a "*.PES" file from a friend, but the characters (TTF) in the pattern are different from the characters my friend used in the pattern.

Why can't I select the 110 mm x 110 mm Design Page Size?
