Not sure this is ready for release yet, this was my first attempt in creating actual UI elements (and still pretty simple ones). There's a new button on the mini map, to the left of the "slide down map" button, which will display a panel for the combat log. It contains all the combat log messages that appear in the middle of your screen during your or the AI's turn. There shouldn't be any incompabilities, except if the space for the button or the panel is already used by other mods. Let me know if you find anything not working correctly.
