At the moment, a vote for an issue feels a little … hollow (or coming from the other direction, rude), given that all votes have equal weight.
Clearly, me scrolling past a good idea and going 'hey, I kinda want that' is different from a user going 'without support for this accessibility issue, I literally cannot use Orion.'
Other voting-platforms I've seen have something like limited votes, but allow you to assign multiple votes to a given suggestion (I personally like this approach) - you can choose to give up your voting-power over other minor issues, but go all-in assigning all ten of your votes to this limitation that is an absolute dealbreaker for you, personally.
Another alternative might be a two-tier voting system, where you have an unlimited number of the current upvotes, but the further ability to assign a single 'dealbreaker' issue for yourself.
This is helpful in two ways:
If I know that I have a differentiated way to express important issues, I can feel more comfortable using the normal upvote-system for things that "would be kinda nice" without feeling like I'm watering-down the feedback system.
This is particularly helpful in the case of 'poweruser features' - a feature might sound work-around-able to the average user, or to a developer who uses a different workflow, and be under the misapprehension that it's no big deal to leave that particular feature out … but for a subset of users, that single feature might be the killer feature that leads to them using (and evangelizing, and paying for) Orion over ten, fifty, or a hundred other fixes or features. That priority-information is best encoded somewhere.
It reduces noise in the conversations - about every other thread I've read on here has somebody posting something upset along the lines of "THIS IS WHY I'M GIVING UP ON ORION 🤬", which doesn't really contribute to the conversation … but also is, in its own way, useful information that it's valuable to collect.
(Call it a stretch goal, but also: if folks have a "THIS IS WHY I'M GIVING UP ON ORION 🤬" button, that could potentially be a different tier of notification - and a chance to re-acquire a subscriber if you do fix the omission they depend on, heh.)
