I'm not blind so for sure I won't really care about accessibility but honest question why not use an ide developed for blind people instead of using the same as non blind people?
Adding accessibility for screen readers is much more difficult to add later in the project lifecycle. Thinking about those design considerations early makes a big difference in how accessible it will later. If developers don't think about these things early, most likely the product will never be fully accessible, ever. Blind people have seen this played out before with other software products and know where this path leads.
(I'm not blind but have worked with blind developers. I'm not an expert in accessibility but I know enough to know how important it is to listen to accessibility needs)
You start an editor with extensibility from day one, as well as theming from day one, as well as multi-platform from day one, etc.
Why should it be different for Localization or Accessibility?
Imagine if you can code screenless. Headaches in response to light? Not a problem. Avoiding screens at night to wind down for sleep? Solved. Eyesight deteriorating (a totally normal thing that comes with age)? No new tech or ecosystem to need to adapt to, everything is already there.
I believe I've said this before, but as sad as it is, every time I hear "Custom UI" I immediately think "Oh great, this won't work". In fact, I'm much more likely to give something a go if it's developed using web technologies. While not perfect, at least I know that there's a chance that it might work. It shouldn't be like that.
Approaches like yours are why people who are differently abled feel left out and like second class citizens a lot of the time.
I recently had a scare with my eyes. Freaked me out. I started looking at my developer tools completely differently. You are not out of the woods buddy. Anything can happen tomorrow. :)
It’s also for users with poor eyesight, colour blind folks or folks with motor impairment.
It can happen to any of us and then you’d be glad that developers are taking accessibility standards seriously.
