This mod should be useful in case of dialog conflicts/problems in quest progression.

Press Shift while clicking a dialog topic to log/paste to clipboard the dialog INFO
Press Shift while activating an actor to log to MWSE.log/paste to clipboard the next dialog greeting INFO triggered by that actor.
Press Ctrl + Shift while clicking a dialog topic to try and add hidden/overridden topics to player known topics list.

The Shift + click topic option and the Shift + Activate option to log to MWSE.log/paste to clipboard the dialog INFO should be generally useful
if you found a dialog topic/greeting info entry having/causing some problem and want to get more information about it to try and fix things.
(the mod INFO ID and sourceMod information would be especially useful to report for help)

If you think you are blocked in some quest because you can't find the proper highlighted topic to click and progress, try using the Ctrl + Shift + click topic option, that could manage to make the topic available.
Don't use this option liberally/without reason though, else you could make available early some topic that was not meant to be available until a certain quest stage, potentially causing opposite problems.
