Recently, the "Sensitive" item in the Object Properties dialog box was changed to "Lock". Presumably this is for consistency with the corresponding layer operation.
The word `Lock' doesn't communicate very well that one can't even select the objects with the mouse (e.g. to view properties), whereas it wrongly communicates that the objects can't be changed.
(Insensitive objects can freely be changed once they're selected somehow, e.g. because they're still selected from when the user changed their item properties, or using Select All, or the Find dialog box, or selecting from the XML editor. I think it would be wrong for the Lock checkbox to deselect things, as that would give different behaviour for clicking Hide then Lock from Lock then Hide, for example, or whatever other changes to the objects one wants to make at the same time.)
We have another padlock icon in the toolbars, but it doesn't mean "The selected object/s are insensitive", it means that the Width and Height spin buttons change in unison to maintain constant aspect ratio.
I intend to change the word Lock back to either Sensitive or Insensitive (or Canvas-selectable?) and change the tooltip for the layer padlock icon to mention the word sensitive. Maybe "Make the selected objects insensitive, i.e. prevent the selected objects from being selectable with clicks or drags in the canvas."
