Respectfully, this may be the case in some instances, but not all. The Bird Dog appeared to have a spate of updates for a while (e.g. up to Spring '21 from what I can see) but these seem to have stopped? The Islander appeared to consume the developers attention thereafter, with minor and now a major update since. However, the Bulldog has only had one minor update (from 1.0.0 to 1.0.1, from what I can see) despite deficiencies being politely, constructively pointed out, in some cases by those with real-world flying hours in her
In some instances constructive suggestions for improvements have been dismissed, ignored or met with sarcasm 
I don't have a problem with a developer (esp. if working solo) working on one product at a time (I admire and appreciate their very hard work and dedication) but I'd appreciate a more level-headed attitude and some open-and-honest responses along the lines of "many thanks for your feedback, improvements will be considered and acted on appropriately sometime after development of product X, which is our focus right now... many thanks for your patience in the meantime" Just my 2p!
