I hope that it's going to read InDesign files, it can't right now.
I don't think that the old ones did. It's also one of the reasons that I think that I'm going to end up just going with a subscription. It doesn't even support PagePlus files right now. They suggest exporting to PDF and then importing. It's been reported to work fine, but I'm skeptical.
UPDATE: Looking on the forums, Chris_K from Affinity affirms "It's not possible yet, plans to be able to in the future"
. Now, what comes of that is to be seen.
He also says when asked about a timeline, "I can't give any timelines for this. 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."
But, reading on, more troubling is this response from him to someone else, "We will not be able to import indesign files on initial release but it is something we are looking to do in the future. For the print optoins my best advice is to go and explore what options we have available already and see if they suit your needs, they are all contained within our print dialog"
What does on release
mean? On commercial release? Or is he just talking about the beta? Hmmm....
