A small annoyance that happens when using kstars' skymap for astrophotography is that when you move around, the sky will move as time passes. You have to manually 'engage tracking' to freeze it. However, if you move again, this engage tracking will be disabled and you are forced to engage it again. I think this should not be the behavior. If the user wants it engaged, it should stay engaged even if you move around.
Already can be done to lock your mount. It's found in the Mount toolbar which you can toggle from Settings ---> Toolbars shown.
