Great idea Flash. Maybe a double badge (a bit like the sheriffs badge for copyright protection). One is that the author has some universal projects, the other is that the author has only universal projects. The badge would be automatically updated (once a week or so) by looking at the "universal" marker on the user's project files.
This would be a great incentive for authors to update their back catalogue. It would also mean that non-english AE buyers could filter search results and even authors down to those that are universal. This would potentially open Videohive wide to the vast non-english speaking market. Do we have to record our user guides in French, German, Italian, Spanish and Japanese and Korean too now?
On that note, a word of warning: This regards sinking prices, rising quality and rising input expectation from authors. A project file seems to get about the same price ticket regardless of how expression heavy / universal / customizable it is. The rationale being that it makes this file more desirable to buyers and will therefore get more sales. But this doesn't work.
There is a danger that Videohive is rewarding authors for having a lower skill level, in that simpler projects seem to have prices that are much higher proportional to the effort involved than those that are complex (and I mean complex in a good way... lots of stuff under the hood that makes the user experience better). Example: some Trapcodey preset logo revealer - $12. Extremely in depth customizable video presentation $25. Price 2x, workload 10x.
Amid all the newcomers and all the great projects that are coming in recently (and the quality bar has gone through the roof for the top 5% or so of files), it's easy to lose sight of how many quality authors are simply disappearing... or not producing files at anything like the rate that they used to. This is a simple factor of the pricing and mechanics of the Videohive site. I know there's a lot of top authors who get pretty fed up with it.
