October 6th: how poor has become this app...

Many crash downs, slowness, various minor bugs.
Until now Ive not yet found how to add pages to an existing doc. It seems impossible, a new doc is created but impossible to add pages in an existing one.
The options and parameters which were available in the V5 were allowing more possibilities to adjust and correct the picture. Now they are very limited.
When trying to delete existing files, oftentimes it crashes.

How come the developers of this app could make it evolve to such a miserable version 6? How the hell they dont put back the V5?? as every body is shouting for this. This is a non sense. Are they forbidden by Apple for some reasons, or what?? Is it pride? Why maintaining this V6 while "the whole word" is ranking it as 1 star only (and if zero was possible we would have done it)
