I feel like I'm grasping at a future elegant interface that's light and wonderful to use, but it occasionally slaps you in the face with either a bug or something unexpected.
Working well 95% of the time over the course of a day is not good enough. The 5% of bugs/confusion is too much.
If I keep it light and mostly single app stages (on my personal laptop) it's usually fine. Moving to multiple 2-3 window stages on my work machine, can get weird and bring out issues.
The big one is that sometimes bugs out and I end up with an un-clickable stage thumbnail stack that does nothing. Futzing about with other stages and windows tends to free it somehow eventually, but this has happened to me many times already in a short period of time, and I don't have a good mental model of what's happening or how to fix it. It's usually a stage with more than one app.
Sometimes a window has disappeared and I don't know where, and I have to open expose to find it. Everything is so managed I'm not sure this is a bug or it just dropping off recently used stages. It's hard to tell.
But outside of bugs, the following kills me...
- If stage manager is fitting 6 stages maximum, and to be productive I gravitate to 7 or 8 logical stages I'm switching between, I end up with a part-hidden mess of obscurity. This is a big frustration, you should be able to page down with the scroll wheel at the side and bring up older stages like you can with the iOS task switcher to bring up previous apps... I'm not saying it has to be 'infinity' long, but the default 4-5-6 stages (depending on monitor size) is too low. I want/need more. I just can't get around **** automatically disappearing. I thought I could, but it doesn't work.
- If you want to drag a window off a stage which has multiple apps, and you click and drag, it seems to always grab the top one, or the last window you used on top on that stage, I think. I want to be able to pick which one to drag off! Right now I have to go to that stage, pick the app so it's top. They go back to the other stage I want to drag it to, repeat the attempt. I can deal with it, but it took me ages to work this out. It's a lot of mental effort. I feel like if the stage thumbnails just went into mini-expose with a cursor hover intent it would be more elegant and quick to pick which one you want.
An easy win in the meantime would be adding the option to right click an application in the dock and pick a "
new window in current stage" option. For finder alone this would save me a lot of messing about. No more of zooming about going to the last stage you had a finder window and then zooming back to where you were, then dragging it off!
That said, I like the concept, but I'm worried people are going to be put off by it in its current state. I think it's just not ready for anything beyond very basic/light use. It removes all the constant paper-cuts of window management but periodically gives you a nasty, deeper infected gash in exchange.
