Today, I was making an invoice using Ulysses and was beginning to get frustrated. I was playing around with various settings/formats and I was having to export the document many times to see if I liked it. I was thinking it would be much easier if there was some way to have a "final" preview window and avoid having to export the document every time. Maybe similar to the preview document window? Maybe both can share the same space and you can change views the same way we change note/excepts preview?
Thank you for the suggestion. A preview feature is already on our list and as far as I know, there will be a third party application soon that could help you here.
