Due to some change somewhere along the road the nudge clock does
no longer fit in the transport-bar on 1024px screen with 100% font-scale,
even if the 2nd clock is hidden.
However, these days it does fit nicely on its default position even
with wide-editor-mixer on a 1024px screen.
Visibility is driven by the currently selected mouse mode.
Visibility no longer depends on entering/exiting the region.
Range mode shows the lines but not the points.
Fixed option text to reflect new operation.
- its now possible to use snap modifiers in combination with others
afaict this hasn't worked for some time.
- use "contains" rather than "equals" during drag. Still uncertain
about this wrt beginning a drag. for now they are all "equals".
- probably solve the "snap modifier modifier" problem using
ArdourKeyboard::indicates_snap () and friend.
- user can abs/rel modifier key in prefs->user interaction
suggested for linux - absolute->alt ignore snap->alt-shift
- Constrained mode works the same as button 2 drag (initial move
sets constraint axis).
Currently we don't do anything special on layering prefs change
(relayer only occurs when each playlist is first edited). The idea here is
that "undo" is still available to restore previous layering in case of any
surprises.
“number of visible tracks”: count automation lanes
as tracks. Distribute equally.
“Summary View”: the visual lane represents both
track + automation. Set the total height.
Left to do: recursive “Shrink” and “Expand” tools
if there is no explicit selection.
Fix several other cases where a single mouse click could cause several
(not nested) selection ops.
Fix missing selection memento for midi notes and midi commands.
Rename some variables.
Fix random style issues.
The user can now replay *all* earlier selection operations until the next
session undo/redo command, or the completion of a new operation.
Nothing relating to selection ops is stored, and selection operation history
is begun on first idle.
Selection operation history is fundamentally different from the history of
operations which act on a selection in terms of both their viewport and the
amount of information required to replay them.
WRT undo, the user of a selection op doesn't care about the viewport state
at the beginning of an op, but rather that at the end of the previous one.
