We already have the possibility to let a user switch between "site dashboard" and "all sites dashboard". It could be nice to let users also pick for instance "Visitor Log of site X" or maybe even any other report.

This was requested by a user for the mobile app but I think it makes only sense to implement it there if users can also pick this in Piwik:

I would love to be able to choose my default landing page (visitor log, in my case).
