affinity-chicken

I just downloaded and installed a trial version of photo and designer and tried to continue working on a project which I started with Adobe products. My first impressions made me seriously thinking about changing to Affinity. However, when it came to export some graphics for the web I couldn't find a preview function. At the end I found others asking for this essential basic function in this forum.
Is it really true that people are asking for a preview and there didn't happen anything since June 2015? Will this problem ever be solved and if so: when?
Thank you in advance

Thanks. I saw Your post from 2015? with reply about this same issue and information that this feature is on roadmap.
Looks like You have another priorities than this, what is fine.
For me preview in export in _photo_ tool is a must have, so I will stick with Photoshop or use GIMP. I don't know any single photo app without this function, so Affinity is quite innovative on this field.
Thanks again for reply.
