It's amazing how you managed to do this! Very nice... although the amount of code needed (svg library + your own) to create the breadcrumb splitter, I think it's too much. I wouldn't do this kind of personalised widgets too often.
Some little things:

• A controlled breadcrumb widget. Instead of having the logic in NavigationBar, having a separate Breadcrumb widget that takes a path of node ids, and renders itself as a series of ToggleButtons and separators, or even better, as a series of extended ToggleButtons that incorporate their separators when appropriate, and manage their state changes on hover, clicking, etc.
• On hover, the separator is not highlighted and looks a bit weird.
  
• I don't know if related to this PR, but grouping nodes no longer works. Links created inside the group are not saved, and the edge stays dashed. I cannot ungroup them either..
  
  
• I see some hardcoded widths and heights

@GitHK @ignapas To be tackled in this PR:

• If I add too many slides, the layout is broken and the next and prev buttons disappear; also the breadcrumb bar on top is not fully visible.
• A controlled breadcrumb widget
• Remove hardcoded widths and heights
• On hover, the separator is not highlighted and looks a bit weird

awesome!!
Sorry, there is something I didn't see before... not so important... there is a problem when you are inside some group views, the breadcrumb disappears and the previous version shows up
