Hello--sorry if am butting in, but I tried version 13 yesterday, straight from version 10, and after a couple hours editing I rolled back to the previous version, because:
- I couldn't anymore rearrange the tabs of open pages by dragging them
- as soon as I started search&replace with the preview panel open, Sigil became increasingly sluggish, and it ended by affecting the codeview window--i.e., lines began to overlap to unreadability, returning to normal only after closing preview.
I am running windows7, only 6gb ram, no additional antivirus nor cloud. And, as I never installed either version 11 or 12 (thanks to this board!) my preferences didn't get corrupted. As a matter of fact, as soon as I re-installed version 10 on top of 13 (many thanks for making that possible without uninstall!) all is again up to Sigil's premium performance--and the memory when iddle (codeview, no preview) has plummetted from around 200mb to 50mb...
Thanks again.
