Please, do not remove it. For most of users, this option is not useful. However, developers need to be able to set the value (usually at a low value like 2 or 3) when the undo/redo has an issue (usually related to object deletion), even in release mode. Sometimes a crash can happen when objects in undo/redo list are deleted, if there is a bug in these functions. -- Jean-Pierre CHARRAS _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@lists.launchpad.net Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
