that I can move text after saving the whole file I know but can I edit it as well?
It would be really bad if there was no way to edit it...
You can resize, move, etc. using the move tool (looks like a cross with arrows in the upper right) but as far as the actual text goes, you can't change it.
To be honest, due to the limited list of fonts (probably due to the limitations of tablet hardware), it's not a big deal to me. If I were to place any text, it'd probably be temporary (preferring to finish it off in Photoshop on desktop) and any text is easily replaceable anyway.
Unfortionalely I don't have Photoshop and I don't like working with my computer ;)
I hope that Adobe will fix the problem soon. The text seems to be an image when I accept the changes (when I zoom in later, the image (or text) pixelates !).
But now I try to not edit the text later on ;)
You are correct, the text is not editable and like an image after you click the blue checkmark. However, you can reposition the text in the image like Warunicorn describes using the Move Tool. More text is editing functionality is something which others have requested as well, please add your vote here too.
