When I send my v19 file to my accountant, I zip the file. That means the 157mb file becomes a 25~mb zipped file.
Why not use the same concept when you first require users to upload the AR Live files?
I'm just evaluating AR Live now and waiting for the company file to upload isn't fun. Also there is no feed back on the progress of the upload. How many more megabytes remain for the upload? What is the estimated time or the average upload speed? Those features will help users not become frustrated at the process.
Sure this stuff might seem like the icing on the cake, but it is actually my first impression of AR Live as I prepare to use it for the first time.
Regards.
