The new page layout is simplistic but the plan is to make a more customized, personal one. GPX traces migration is not yet done but at least post and readings are. One of the side effect is that build time is greatly reduced.
On the overheads, post creation is a bit more tedious because I have to define the proper name including date manually while Octopress has a rake task for doing it. I also had to write my custom deploy script, because since I rely on latest versions of Jekyll I have to build locally.
