I tried to engage and be constructive in my reply with ideas
Broadly my response was
Leith Walk should be 1 lane, with loading lanes where space permits (most of it)
There should be cycle lanes the whole way down
The central reservation should be extremely wide to facilitate tiger crossings of the tram line at intervals similar to pedestrian crossing frequency just now
Peak time traffic ban
I pointed out that the scheme as proposed does not comply with council guidelines nor any previous work done in Leith Programme 1-4
I provided some drawings to support my ideas because this stuff is hard in writing. They all are minimum-widths for the named segment.

I made the case for a (narrow) 2 way lane on Constitution St, at the expense of pavement width
I argued for this lane to continue all the way to Melrose Dr via Ocean Dr in some form (this is the way I cycle to Ocean Terminal, it is much quieter and safer than Great Junction St)
I objected to the need for a new road junction with detriment to cycle amenity at the mill end of Melrose Dr as it is currently a cul de sac
Only in the passing was I able to mention I support the tram extension to Newhaven if done correctly, the consultation focuses purely on the design as presented
