Update 18th November 2019: Since there are now many more suggestions on the platform, the vote count per user has been increased from 10 to 25. So if you had previously used up all your votes, you should have another 15 to distribute to other ideas. Please bear in mind the advice in the original post and cast your votes wisely, so as to avoid wasting them on unlikely or infeasible ideas.
I'd add there is a huge number of suggestions filed on there (around 600 at time of writing). Using a crude calculation, in the approximately 2 and a half years since the platform was set up, we've shipped 136 user suggestions. I think that's a pretty good result, but it means as a small but highly productive company we're shipping about 54 suggestions per year. At that rate it would take 11 years to implement all the suggestions on there, not including further suggestions filed during that time. Please be mindful if you decide to post a new suggestion that due to the numbers involved, it's unlikely we will have the resources to address it unless the suggestion is either very quick/simple, or extremely valuable to the vast majority of our customers.
