I am really enjoying using Affinity Publisher Beta, it is just as easy and intuitive to use as the old PagePlus series from Serif. However there are a couple of features that are currently missing that I used frequently before.
For many years I have been used to quickly clicking an "Alignment" button in the Character/Paragraph format toolbar which quickly centred, aligned objects (including text) to left edge, right edge, or vertical centre, top, or bottom of guides or margins. Currently it is possible to align things using the justification tools but there are not as many options.
I find the work space / desktop area in Affinity Publisher Beta very restrictive with all tools permanently open. PagePlus allowed the panels of tools to be shown or hidden with a single click with panels sliding in and out from left or right. I haven't found this available in Affinity Publisher via the "View" options either.
