- Why does the size of the selection overlay no longer fit to the buttons on it?  Given that the button contents of each selection overlay should be fixed (only disable/enable changes), the overlay size should be pre-computable and fit to the size of the controls on it.
- In the description, need more detail.   For example, "Rename block from <> to <>" - if the from <> is empty/untitled/default, then it's fine/preferable to say "Name block <>" instead of "Rename...".
- When creating a new route, it should say "Create route from <block>:<port> to <block>:<port> in scope <>".
- It's confusing that a single click on the timeline icon restores HEAD to Latest.  Instead of a single click taking us to HEAD, we should have a small button in the timeline popup that allows you to seek to HEAD.
- Once the timeline popup allows you to open it when at a different Rev than HEAD, it should be visually obvious where you are in the timeline.  The current rev that is visibale on the canvas should show up in the timeline popup as the selected rev.
- There are two popup actions on the history items.  There should only be one - a single popup menu behind a "..." button that allows you to a. View a rev, Make a rev current, Tag a rev.  Single clicking on the entry in the list should default to viewing that rev.
- The changing behavior of the undo/redo buttons is confusing.  When in "view a rev" mode the undo/redo selection overlay should change to have tape player like controls (Single step backwards with a |< icon, single step forwards with a >|, and a seek to the end with >>|, which returns us to latest)
Going "Up" from the top of the diagram does not work - We get an extra block "Top_1", but the rest of the contents remains.  For now, the acto of creating a new layer in the diagram (by demoting the "top" via embedding) should be disabled and not available from the "Up scope" button.  This should move to another location on the UI (TBD - but probably the navigation popup).
- The log entry for editing the text of a text box should be more descriptive, for example "Edit text in scope <> to <>".
- The tag for a revision is not visible.  There is no contrast relative to the background to see the text.
