Spaces support was added in v2. During development I noticed an edge-case: if you invoke alt-tab during the space transition animation, it will bring alt-tab window on the previous space, then when you release the shortcut, it sometimes send the window in the void: you can never access it again by any mean.

At trigger time, alt-tab records the current space. I think when done during a space transition, it records the "transition space". I read in another codebase that macOS has a fake space for transition periods.

Even if this impactful bug doesn't happen, the UX is still bad because the alt-tab window is on the previous screen, but the user is still interacting with it, so when they release they get an unexpected behaviour.

HyperSwitch works around this issue by buffering the shortcut, and only triggering when the space transition is done. I think that's the way to go. Either that or ignoring triggers during the transition.

### BREAKING CHANGES

* Instead of asking the OS about the state of the whole system on trigger (what we do today; hard to do fast), or asking the state of the whole system on a timer (what HyperSwitch does today; inaccurate) - instead of one of 2 approaches, v3 observes the Accessibility events such as "an app was launched", "a window was closed". This means we build a cache as we receive these events in the background, and when the user trigger the app, we can show accurate state of the windows instantly.

Of course there is no free lunch, so this approach has its own issues. However from my work on it from the past week, I'm very optimistic! The thing I'm the most excited about actually is not the perf (because on my machine even v2 is instant; I have a recent macbook and no 4k displays), but the fact that we will finally have the thumbnails in order of recently-used to least-recently-used, instead of the order of their stack (z-index) on the desktop. It's a big difference! There are many more limitations that are no longer applying also with this approach.

### BREAKING CHANGES

* bump major version
* Instead of asking the OS about the state of the whole system on trigger (what we do today; hard to do fast), or asking the state of the whole system on a timer (what HyperSwitch does today; inaccurate) - instead of one of 2 approaches, v3 observes the Accessibility events such as "an app was launched", "a window was closed". This means we build a cache as we receive these events in the background, and when the user trigger the app, we can show accurate state of the windows instantly.

Of course there is no free lunch, so this approach has its own issues. However from my work on it from the past week, I'm very optimistic! The thing I'm the most excited about actually is not the perf (because on my machine even v2 is instant; I have a recent macbook and no 4k displays), but the fact that we will finally have the thumbnails in order of recently-used to least-recently-used, instead of the order of their stack (z-index) on the desktop. It's a big difference! There are many more limitations that are no longer applying also with this approach.

### BREAKING CHANGES

* bump major version
* Instead of asking the OS about the state of the whole system on trigger (what we do today; hard to do fast), or asking the state of the whole system on a timer (what HyperSwitch does today; inaccurate) - instead of one of 2 approaches, v3 observes the Accessibility events such as "an app was launched", "a window was closed". This means we build a cache as we receive these events in the background, and when the user trigger the app, we can show accurate state of the windows instantly.

Of course there is no free lunch, so this approach has its own issues. However from my work on it from the past week, I'm very optimistic! The thing I'm the most excited about actually is not the perf (because on my machine even v2 is instant; I have a recent macbook and no 4k displays), but the fact that we will finally have the thumbnails in order of recently-used to least-recently-used, instead of the order of their stack (z-index) on the desktop. It's a big difference! There are many more limitations that are no longer applying also with this approach.
