Suggestion for rasterize effects in export

[grs84pl]

Hi!
First. Sorry for my english.
Second.
I've been working with Scribus and printing my works in commercial printers for two years.

Main problem with Scribus are effects that are not rasterized, before creating PDF.

I've got two suggestions that in my opinion might improve handling the printing process.

I.
Adding option that exports TIFF in CMYK with bleeds, markers etc.


II.
Adding option in F2 menu that change specific object or group of objects in image.


This would reduce problem with transparency, gradients, bluring.. It would be much help for ppl that prints in commercial printing.

BTW, great job!
