You started a support case with your feature request?
It's
exceedingly rare for P1 not to reply to a support case with 24 hours (usually much sooner). What's your support case #?
Maybe you emailed the general email box for P1? If that's the case it's likely to take a while to route to the appropriate person.
Go here:
http://www.phaseone.com/en/SupportMain.aspx and select Contact Support. I promise you'll get an answer and every feature request is in fact logged for when they sit down to discuss priorities (nearly every feature is possible it's simply a matter of how much work is required to implement it, maintain it in the future, check it for bugs to make sure it is stable, etc). It's a small company and I've found them very responsive to specific requests. Sometimes it's frustrating how long it can take to be implemented but
many of the features in the current version are features I've seen requested by users and implemented as a direct result of the requests.
