I'll update here with more if I find more. Me too! I'm hopeful that the suggestions in this thread get implemented in the next month or so, otherwise we're gonna have to seriously start thinking about alternative frameworks. We should adjust some dom structure to enhance it. Considering not breaks current behavior, it may not fast for it but it's in progress.

Thanks for the update zombieJ. I appreciate that the antd team is working on this. I've also noticed that the expandable rows in the Table component aren't accessible. There is no way to expand them via the keyboard.

Menu In using a screenreader to test this, I discovered that Menu. Item is being read as a form element by the Screen Reader, when it really shouldn't be. It makes it much harder to navigate a website, as the screen reader tells you there are form elements when there aren't.
It lists each of them as "Dashboard menu item", "account menu item", etc. Thank you for continuing to be so awesome. No individual ant remembers the colony's current place in this pattern. On each forager's first trip, it tends to go out beyond the rest of the other ants travelling in the same direction. The result is in effect a wave that reaches further as the day progresses. Gradually the wave recedes, as the ants making short trips to sites near the nest seem to be the last to give up.
From day to day, the colony's behaviour changes, and what happens on one day affects the next. I conducted a series of perturbation experiments. I put out toothpicks that the workers had to move away, or blocked the trails so that foragers had to work harder, or created a disturbance that the patrollers tried to repel.
Each experiment affected only one group of workers directly, but the activity of other groups of workers changed, because workers of one task decide whether to be active depending on their rate of brief encounters with workers of other tasks.

After just a few days repeating the experiment, the colonies continued to behave as they did while they were disturbed, even after the perturbations stopped. Ants had switched tasks and positions in the nest, and so the patterns of encounter took a while to shift back to the undisturbed state.
No individual ant remembered anything but, in some sense, the colony did. Colonies live for years, the lifetime of the single queen who produces all the ants, but individual ants live at most a year. In response to perturbations, the behaviour of older, larger colonies is more stable than that of younger ones. It is also more homeostatic: the larger the magnitude of the disturbance, the more likely older colonies were to focus on foraging than on responding to the hassles I had created ; while, the worse it got, the more the younger colonies reacted.
In short, older, larger colonies grow up to act more wisely than younger smaller ones, even though the older colony does not have older, wiser ants. Ants use the rate at which they meet and smell other ants, or the chemicals deposited by other ants, to decide what to do next. A neuron uses the rate at which it is stimulated by other neurons to decide whether to fire.

In both cases, memory arises from changes in how ants or neurons connect and stimulate each other. It is likely that colony behaviour matures because colony size changes the rates of interaction among ants.
In an older, larger colony, each ant has more ants to meet than in a younger, smaller one, and the outcome is a more stable dynamic. Perhaps colonies remember a past disturbance because it shifted the location of ants, leading to new patterns of interaction, which might even reinforce the new behaviour overnight while the colony is inactive, just as our own memories are consolidated during sleep.
Changes in colony behaviour due to past events are not the simple sum of ant memories, just as changes in what we remember, and what we say or do, are not a simple set of transformations, neuron by neuron. Instead, your memories are like an ant colony's: no particular neuron remembers anything although your brain does.
