Ironice

At last!! Thank you for Publisher!
My first thought was how do I import my indesign files? At the moment there is no 'Import' button and 'Open' an indesign file shows a greyed out 'filename.indd'. Hmmm?? But because I always create a pdf from my indd files, I found I could 'Open' the 'filename.pdf' with no problem other than it opens as pages not facing pages. I then clicked the 'Document Setup' tab and changed the 'Layout' to 'Facing Pages' and I now have my indesign page saved as 'filename.afpub'.
Good news!

I can't give any timelines for this (IDML import, not INDD). It's being worked and will be in an update when it is considered working and relatively stable. But I would be talking more than a few weeks in not months, It's not a simple thing to just implement

One of the features that would make the iPad version of Affinity Photo much nicer to work on is the ability to quickly flip the canvas horizontally using a gesture. I feel that this is a very important feature and I use it a lot in other apps. I use the horizontal flip when I'm drawing because it helps me see mistakes and makes inking/painting much easier since it gives me different angles to work on. I can imagine that this feature would also be helpful for photo editing because it makes it easier to check the work for any mistakes or areas needing improvement.
So, please give us a gesture to flip the canvas horizontally. It would make a big difference! Thank you Affinity Photo team!
