# Short term goals
- add "Help" entry to menu bar. Should open a popup window with a one page description of how to use it. Use HTML or Markdown text.
- add dialog when exiting asking if file should be saved when it is modified, similar dialog when opening a new file
- add CTRL-q hotkey to log windows so you can exit the entire application (add do you really want to? dialog to this)
- add "render" dialog where a "write_dump image" can be triggered. dialog should offer options for size, zoom, rotation, colors(?)
- add "syntax check" with enabled "-skiprun" flag
