Let me continue here in this thread with some thoughts that are also closely related to the new voting feature: http://forum.gtdnext.com/t/feature-idea-voting-now-live
I think it is best for everybody to be very clear about the fact that some important features have already come to be taken for granted.
In cars, the windscreen wiper is an absolutely brilliant feature. I assume it must have been the wonder of the year at some stage. Truly superb in its simplicity and effectiveness. Would anyone choose a Volvo today because it has windscreen wipers? No; all cars have that. Would anyone refrain from buying a car that does not have windscreen wipers? You bet!
Put simply: You cannot gain customers by having ubiquitous features, but you sure can lose customers by not having them.
In GTD apps, the current state of affairs is, among other things, that people want to be able to read their tasks from a computer, tablet or phone. There is no question about that. And of course they want to have their lists sorted in various ways, depending on what they are looking for at the moment. And so on. There are myriads of "features" that are already ubiquitous today, not really considered notable features if you have them, but considered notable shortcomings (lack of polish) if you don't. How is a vote on individual features going to change any of that? Right now there are votes spreading between phone apps, attachments and sorting mechanisms for lists (no, sorry, just the next list). How can you even compare those features and regard them as alternatives?
There is one very expensive way to be successful in terms of market share. Implement all the polish (features) you have ever seen in any app. At least nobody will be turned off by the lack of anything. Would I recommend this avenue for you, though? No, it will probably be too expensive.
And there is a sure way to lose, too. Be stingy on the general polish and have nothing truly essential that stands out.
And there is at least one way to win. Have an acceptable level of polish across the board, but make sure you have some top notch polish and real innovation concentrated in some "area of functionality" that at least some significant minority are starved for. Example (not recommended for you, but still a good example): Zendone and IQTell are capitalizing greatly on the fact that a significant minority of users are virtually dying for integration of their tasks with their reference and support information (email, Evernote). These apps both have shortcomings (lack of normal polish) in some areas, but their fans accept this because their desire to to integrate reference information is so huge. Both apps have tons of different features centered around reference integration and the associated workflow (and have spent tons of manhours developing it, too). Another "area of functionality" that I would not recommend for you either, is performance monitoring. This is often requested in forums (pomodoro timers, logbook statistics and what not). Doit are working hard to innovate in what they call "reviews" (historical reviews), showing pie charts of completed actions from the past day, week, month etc. You'd be a late starter in all these areas (and I personally also think these areas are of minor interest).
But wouldn't it be absolutely great if GTDNext, in the same way, could tap into some virgin "area or functionality" and be simply the best, or the one and only, for those users who really want plenty of functionality in a given area. From where GTDNext is standing at the moment I can see at least two simple and obvious such "areas of features", but I realize that success depends on the creators also being willing to be creative in that particular area. Inspiration and love are important.
Does GTDNext have any "areas of features" where you plan to excel significantly and have a true impact on people's productivity?
