I don't fully understand... are you talking about Git submodules? Or just allowing to generate the docs for any Ruby project? The latter is already high up on the feature list... :)
(feel free to reply in the Disqus comments on ruby-docs.org, I don't check the comments on HN very often)
Big fan of Linux (and in turn FOSS projects) so I'm a KDE + Ubuntu (moving to Debian when I can get all of my PPAs in easily) kind of guy. I use Krita/Karbon for slicing up PSDs and making quick vector images, Pencil for wireframes and light mockups and mainly Konsole, Vim and tmux for all of my webdev works (as well as Chrome and Firefox).
As long as you conform to standards, webdev is easy.
I use KDE mainly because it feels a lot faster than GNOME and Unity and because it moves out of the way when I don't need it. And the smart-as-shit rendering engine for Oxygen makes GNOME apps look native to KDE so it's like I'm at home. I use my laptop for gaming and work.
Enough said, Macaw is going to be one of those tools that separate incapable designers from the ones who know why flexbox is coming to be and what it means.
I'd like to nudge in one thing: option flexibility. I'm still downloading and about to try it out; but I hope that the setting does allow the user to tweak everything they can tweak and not hide options away for the sake of hiding things. My personal thing, but it's shared with many, is that flexibility can lead to a personally complete design.
Flexibility is definitely something we try to be opinionated about. We don't offer a lot of easy GUI customization out of the box, but you'll find that there's quite a bit hidden beneath the surface or is easy to code up yourself.
If you're really interested in a completely customizable and hand-tailored OS, I'd honestly suggest you look into something like ArchLinux or Gentoo[2]. Both platforms have made available most of our applications and components, so you can pick and choose to build the desktop you personally want :)
Pantheon's Arch Linux support is not finished - I'm pretty sure you can't run Pantheon on it. However, on Gentoo I'm sure you can.
Besides that, we do offer some customization, you just have to use dconf-editor to change the configuration keys and not a GUI for several things. And there's also "elementary Tweak" which adds even more configuration.
I'm downloading this now and going to throw it up in a live VM. To be honest, aside from the work-space management and what not in the video; that desktop looks close to my KDE 4.11 desktop here.
Yeah, it's due to the graphics card. I didn't find that exact one with a higher resolution. Personally, however, for web dev, it's the perfect sign since it's right in the middle (closer to phone/tablets). I had a 1920x1200 before (Dell) but now I love this and not worrying too much about testing on devices.
