Regarding Roadmaps in Software development to share with customers..... Never....maybe an informal for development Team. Certainly not customers.SkyDemon has already shown in 'spades' that it is customer aware, they allow customer suggestions and invite open and honest feedback.
After 40+ years in Software and Hardware development business from late 60's I can tell you from experience that the Customer base will run you ragged for and with development ideas and requests for direction. It only muddy's the waters and spoils the product for many 'normal' users.
Ask Apple or Microsoft for a detailed roadmap and see the response!
Keep making suggestions. To date the SkyDemon response has always made replies or comment and Tim in particular is always ready to respond.
Tim....keep making these surprises!
