Installed the new nightly yesterday. The object snapping to guides, margins, etc. improved considerably.
In addition, this version is a lot more responsive and a tad faster. Already made a new promotional piece with it, will have it printed next week.
A big thank you to the developers for this improvement!
Seems that the memory management of Scribus had been improved as well: After closing Scribus, the »used memory« drops down to the level as before starting Scribus.
I wish all programs — particularly the genuine Apple apps like Pages, Numbers and Notes — would behave the same way. I guess the Apple developers could learn a lot from the Scribus developers ;-)
