Designing multiple document interface for Synfig Studio is not an easy task:
The parameters panel and time track panel eat too many spaces. If we provide parameters and time track panels (widgets) for each opened docuemnt, there will be small space left for artwork content. I don’t
have any good idea currently in my mind.
The solution currently I have is:
Parameters and Timetrack Panels(windows) are separated from document/canvas window, and they are linked to the document/canvas window currently activated, and only one document/canvas can be have activated status in a time.
So time for different document/canvas is different.
zoom, rotate, pan, and ducks toggle status, guideline etc. are localized, that means they are different in different docuemnt/canvas window. (The question brings up here is: should we save these status in sifz documents). For Local Toolbar conpects, see the canvas window design and layer window design
good idea.
