For me, the problem is not to have a global or per screen undo/redo list, but what an user is expecting when undoing/redoing a change. We *always* expect to undo the last change. Any undo/redo system has this behavior. Now consider an editor (the schematic editor with 3 sheets for instance, but this is also the case of text editors with 3 files opened and currently edited). 1 - in sheet1 you call a tool (component table editor, automatic annotation) which modify all sheets. 2 - after that you enter sheet2 and make new changes then sheet3 and also make new changes. 3 - back to sheet1 and try to undelete the latest change in this sheet: this is the global change (i.e. annotation). This is possible in sheet1. But how can you undo this annotation in others sheets: this is not the latest change and cannot be undone safely (you can have deleted/replaced/edited a symbol in other sheets, or deleted a sheet): what is the actual meaning of "undo the annotation" in other sheets). And ultimately: What a undo (and therefore redo) command must undo: 1 - the latest change in the full schematic (global undo/redo) or 2 - the latest change in the currently edited (active) sheet (local undo/redo) This is a choice, and the answer is for me not trivial. It could be worth to know what is the option for global/local changes in a schematic hierarchy in other schematic editors. Multi-file text editors can undo the latest change only in the active file, not in all opened files. -- 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
