2. Undo Option: It would be great to have an option to undo the last action. I have inadvertently deleted tabs, removed drawn objects and having the option to undo the last few actions can help quickly restore the state.
3. Move Chart Tabs between Windows: It would be nice to move Chart Tabs between Windows. Drag and Drop would be be the most convenient. If that is hard, an option to select an existing chart window from the right click menu would to move would also work.
