Welcome to ClearOS and nice post.
In fact, your suggestion is exactly 'in the works'. In the 6.3 beta, there are new tags introduced in the Marketplace Details section...one for 'Warranty Policy'...and another for "Support Policy".
I'm thinking of using an icon system to explain at a glance what an app's policies are wrt to these two fields. Still mulling it over, but for "Warranty Support", something like this:
N/A - Not applicable...app is free
Red 'X' - No refunds/returns
Green '24hr' - Full refund, no questions asked, within 24 hours of purchase
Yellow '30d' - 80% refund, explanation required
Those tags are just suggestions at this point.
For Support Policy, a similar color-coded system that indicates where you can go for support. For example:
Green - Community Forum support
Blue - Developer can be contacted via email for support
Red - Developer can be contacted to request paid support
Orange - ClearCenter will provide best-possible support under terms of your Professional Subscription
Black - ClearCenter can be contacted to provide support on consulting basis
We'll have a binary selector here...so an app could have Green and Blue...or Green, Blue and Orange or Green and Orange etc., depending on how the developer wants to model support, and how ClearCenter perceives how much support could come in for an app, and how complex it is.
Here's a good example of why we'd want to go this way...Someone creates a VoIP app around Asterisk and places it in the Marketplace for $20. Someone buys it, and bases their business phone communications on it. We don't want the user thinking they can lean on us while we drop everything and try and fix a phone system we're not familiar with under a $480 all inclusive support plan. So in this example, Green, Red and Black would be appropriate, given that there's no way support could be included for $20. That figure represents the time savings to install Asterisk or a PBX/VoIP stack from source.
Does this kind of system make sense to everyone? Helpful? Too complicated? Of course, there will be a supporting web page detailing the colour coded icons out...that has yet to get created, but is my very next task once I fix Marketplace version control.
