Hello,
Last week, I was taking my spare time on improving jack button by replacing
it with toggle button[1]. After that, I've been playing with it and
thinking further:
1) the usage of colors(red and blue) of icon seems inconsistent with the
one of animate mode button. Regarding the colors usage, there were some
discussions before in our forum.[2]
2) the offset widget is hidden by default, and shows when user enable jack
by toggling Jack Button (now it is toggle button). one canvas window,
offset widget will short the timeline widget, it is not good but still not
bad from usability's perspective. But when it behaves quite negatively on
Preview Window, when user trying to enable Jack, the offset widget will
shift the Jack button suddenly: you click it, and it moves out of your
pointer.
If we show offset widget by default, it eats too much space of canvas
window toolbar. On preview window, it is not a big deal, so how about just
showing offset widget by default on preview window, and keeping it hidden
by default on canvas window toolbar. I personally don't like this solution,
it makes same control has different UX.
So there is one proposal comes in my mind, it would be (I hope) much simple
and clear if we use adjustment widget and a drop-down instead of a dial
widget (a toggle button combining with offset widget). You can refer to
Zoom Level widget in Preview Window [3]. When the value of adjustment is
set to (Mute), the Jack is disable, otherwise, it will be enabled and be
offset to corresponding value.
Disabled : [ Mute | v ]
Enabled : [ 0.00 | v ]
Offset : [1.00 | v ]
