ISSUES: When formatting text in the textbox the format is lost if the size of the text is changed after giving it format. It should not.
As a tip, the 'line spacing' tool should not go as precise as 0,01 per step, that is not useful (as the text size, 1 per step should be OK).

When editing (typing) a text box from a page, and want to edit another text box from another page (typing) there is an error that is not user friendly. The text box can not be edited until the previous textbox from the first page is 'closed'. It should let edit text from one or another from all along the pages, no matter what page, not just focused on one page.
