Hey,
in the last version I had no problems setting the day start time to whatever time I wanted. I usually play from like 1pm till 6am in the morning, so about half of the work day is actually in the next day. I know I can set this to be shown in "today filter", but it is not shown in the "Session by day" or any other filters... I don't like it, because many times I want to see how I did on specific days and I get wrong statistics because of this.
Why don't you make the "set start of day hour" to be used in all filters, not just in today's?
Thanks, Jure
