No worries David. Just wanted to add some important context that I felt was missing in your assessment.
That said, your question is a fair one.
There's something else that might shed light on the answer. For a while there wasn't a whole lot of SB feature development going on.
There were a couple of reasons for this, not the least of which was the condition of the codebase. SB was originally written 14 years ago without the benefit of any frameworks, libraries, and tooling. This made updates time consuming, error-prone, and almost impossible for multiple devs to work on simultaneously.
An effort was undertaken to remedy this by rewriting the code from the ground up. The recent v4 release is the product of that considerable effort.
While we now have the advantage of a sane codebase upon which to continue to build features, there is also an adjustment period to contend with since in some ways this is a new product with new bugs and quirks to iron out. We also had to ship v4 with feature regressions because of time pressure due to Chrome deprecations. The alternative was data loss for a large portion of users, so not much wiggle room there.
Consequently, there's been a significant follow-up effort to address feature gaps and inconsistencies with v3. Most of our work for the past 3 months has been focused on just that. v4.0.4, which is being submitted to the CWS today, is another big leap forward.
All that said, there remains a lot of work to do, and that's always going to be true. Any software product at this scale will naturally have a perpetually substantial backlog. It's important to understand that most of the work being done involves just ensuring that everything functions as expected, is performant, robust, secure, etc. That's effort that is effectively invisible to users, as it should be if we're doing our jobs right. Point being, feature set is only one part of an equation that is much more elaborate than many folks realize.
Finally, when you're comparing two competing products (software or otherwise), I get that it's natural to focus on deficiencies, but qualitative comparisons tend to be skewed when you're failing to consider the bigger picture.
