This required various changes to various parts of the infrastructure (mostly using paths to finding the "root project" of any given object throughout). Now theoretically infinite projects can be opened and accounted for at any given time.

/**
|
|
* @brief A dialog for editing Sequence parameters
|
|
*
|
|
* This dialog exposes all the parameters of a Sequence to users allowing them to set up a Sequence however they wish.
|
|
* A Sequence can be sent to this dialog through the constructor. All fields will be filled using that Sequence's
|
|
* parameters, allowing the user to view and edit them. Accepting the dialog will apply them back to that Sequence,
|
|
* either directly or using a QUndoCommand (see SetUndoable()).
|
|
*
|
|
* If creating a new Sequence, the Sequence must still be constructed first before sending it to SequenceDialog.
|
|
* SequenceDialog does not create any new objects. In most cases when creating a new Sequence, editing its parameters
|
|
* with SequenceDialog will be paired with the action of adding the Sequence to a project. In this situation, since the
|
|
* latter will be the main undoable action, the parameter editing doesn't have to be undoable since to the user they'll
|
|
* be viewed as one single action (see SetUndoable()).
