A few items for consideration for the user interface. COMPILER WINDOW 1. Add 'search & replace', similar to the other windows. (Disrupts work flow to open config files in the text editor each time.) 2. Allow the split pane bar to move up and down the window. The editing area is usually too small. As a compromise, having an upper, middle and lower position would be a great help. ALL THREE WINDOWS 3. Add two buttons (or menu or key combinations), -one to comment out the selected block of text (add # to the start of each line), and -one to uncomment the selected block of text (remove the first non-space or non-tab character from the start of each line, provided it is a #) 4. In the case of the MAP EDITOR the actions would be. -Comment out the selected object, and -Uncomment the selected object This would allow temporary hiding of an object without having to delete it and completely redraw it (or find it's code in the data file and copy it elsewhere for safe keeping) Comments?
