Bug Fixes for next update.

Hi can we please fix two things for the next update. 

- Export to pdf .. currently settings defaults to last previous file you were working on. 
So if last week i worked on a file exported page 1 of all. next week i may go to work on a diferrent file and that setting is still to export page 1 of all. - Solution is to have it default to the previous setting used of that same document.  not whatever last document.  (This has caught me out several times when I send a pdf off to someone and it only has one page in it which was puled in from as setting I may have alloctaed on a different project weeks ago). 

- Shift plus direct selection tool. (a) - when selecting multiple objects in this mode + holding shift.. some dissapear out of the selection.
