Icon size and formula editor settings


I am new to Amibroker and was wondering if the following is possible:

  1. Change the icon size and not having to do it every time the program opens. There seems to be no default size for the icons, which are way too small on my MacBook monitor. So for my only option has been to change the icons every time I launch Amibroker (>Customize>Options).
  2. Is there a way to tell the AFL editor not to automatically open a new file every time it is launched? I.e. only though >File>New?

Thanks for any help
