I'm not sure I follow you... are you saying that if you have multiple tabs, one pointed at 127.0.0.0:8000 and one at flotilla.la/shipshape the later does not work?
... hum, it works here, in Epiphany at least.
what you can try is this:
curl -sS get.pimoroni.com/rockpool | bashthis will pull the latest flotillad (which at present is the same as what is in 'pre'), from the new repo as we just switched source repository for the installer. It will also flash your dock to version 1.14 which is the firmware that we use internally right now for testing, and will likely be the supported tie-in with the next version.
As noted above, we are still working on some parts of the jigsaw, but you can start using the 'rockpool' installer in the fashion I outlined above, there may be some rough edges but it should be a working environment (since every change we make right now is being checked through it).
... but note again that cookbooks are WIP, the goal right now is to get everyone willing to start using what we see as 99% of the upcoming update (bar cookbooks) up to level so to speak. You will need to continue using http://flotil.la/shipshape for the time being though, since we need to keep the original URL up for those sitting still until we have the cookbooks out. Not that I think anybody should, there's not a lot you'd lose in the process migrating now, and you'll gain much in term of experience with rockpool itself.
