Thanks for pointing this out! When you select all to you just press on the text for a few seconds. It seems as if you do it long enough that the entire text is selected (without moving your finger). This is a nice feature. On my android phone, if you press on text, it brackets the word you are pressing but the bracket does not change the longer your press. Instead you have to move the brackets to copy more text.

Anyways, Jolla should still do something about directly emailing a note. I'm sure it will be addressed eventually.
