I have a problem with my gantt chart.
It looks squished because i am specifying timeframes in weeks, but they are shown in days.
Therefore, the milestone rectangle looks weird.

I already tried to set time slot unit to week, but unfortunately this key is not available.

What are my options?

The question PGFGantt Compressed Calendar by week? seems to be related, but I think I actually applied the solution and it is not that useful in my case, because I have a lot more frames causing the problem.
On the other side I am not able to increase x unit because then the chart does not longer fit the page.

May be as said in the pgfgantt manual (under the section 2.7.3 Options: Chart Element Positioning), we could play with milestone left shift =<factor>, milestone right shift = <factor> to relax the squished representation.

this gives you:

we can get:

PS: I also believe that bar/group left/right shift can yield these smooth links (of course neither the bulge not the rounded corners ;-)).
