Patrick, could you tell us if you plan to add GREP (e.g. like the one in InDesign or JavaScript) to Publisher. It is a very important question for all potential Polish and Czech users of Publisher. In these two languages there is something which is called "orphans". The "orphans" are individual letters or digits at the end of the line of a text (see the included picture). It is a typographic error in Polish and Czech language. Adobe never implemented any option in their paragraph composer for removing the errors. But thanks to GREP one line of a code resolves the whole problem in InDesign. It is no problem if you work on a several-page document, but if you have to remove "orphans" in 500-pages book manually it becomes a very tedious work. Regular Expressions are a very useful magic programming tool.
Please, make GREP one of your priorities... or add an option in paragraph composer for removing "orphans."
The second thing very essential for many languages is support for Hunspell. The support for Hunspell will provide the spelling check and correct hyphenation in the languages (Polish, Hungarian etc.)
Great thanks for the Beta.
