Hello everybody (English is not my native language, I hope you will understand me clearly.) I noticed the displaying time of the tree structure is not the same when just navigating inside bookmark's folders and sub-folders, or when MOVING a bookmark (new or existant, doesn't matters) inside. The issue is that you need to be precise when moving it into sub-folders, because any error and all the tree structure disappear and you need to do it again (very boring when there is 3+ sub-folders...) So, what I ask is : is there a time parameter in about:config (like register modification for windows start menu delay time), not to display a folder (the default time is OK), but to make it appear longer (it disappears too soon when moving bookmarks). I made a woooonderful screenshot (I know, I should be an artist :P ) wich I think is easier to understand! BTW, a "bonus" issue : you need not to move "in diagonal", because then the menu will immediately disappear, any tips for that? (Other than "move it straight" ;-) ) I hope you'll understand my question, thanks for the help!
