Arrows styleing and multi-fonts

The first impression after 2 other mindmap apps - it’s blazing simple. However, would be great to have a few features that are not yet available:

  1. It’s a bit frustrating that it can’t used multiple fonts within document.
  2. When exporting to .pdf file, some wiered lines appears on the shadow.
  3. Only streight arrows. In some cases you have to duplicate the first bubble instead just draw curved arrow.
  4. Arrows can’t be colored.
  5. For some reason it is impossible to print a normal single quote. If you copy it from the code editor, you can see that the symbol is there (Consolas font).

  6. It does not remember the last “Save as type” format. When exporting image, it’s .jpeg format by default.
