Working on mobile / responsive navigation (part 2)2 December 2016
Work is advancing on the responsive update. All the pages are being worked over; I'm using Bootstrap to refresh even the basic things like the sign in form... which end up much more usable on a small screen.

The navigation is working. I spent a lot of time thinking about what kind of navigation to use but eventually I've settled on making my own. A relatively simple dropdown. One on the left for the main navigation, and one on the right, for the account options, with the Koohii logo center (working as the "home" button).

There are some pretty cool "slideout" navs out there... but who knows how it behaves when I have more interface on screen like the flashcards? And if something doesn't do what I need it to do, updating the code will be a headache.

Pledged for Font Awesome 5 Kickstarter (19 hours to go!)30 November 2016
Thanks to everyone who supports Kanji Koohii ! I've just pledged 20 $ today in the Font Awesome 5 Kickstarter for the Early Backer Reward.

I saw this Kickstarter earlier and shrugged it off thinking the free version was enough but I'm also interested in the SVG icons and I thought it was too good to pass up. This website currently uses the free version of Font Awesome. With the Pro version I will have access to many more icons, and potentially use SVG icons as well.

If you're looking for icons (both font and SVG) for your projects / designs you can still help them reach the 1,000,000 $ goal and get the a Pro license for just 20 $ !

Rethinking the main navigation16 November 2016
So I am knee deep in the "responsive" improvements to the website and rethinking the navigation to better support small screens. Today after reading some interesting UX articles relating to the "hamburger menu", I decided to experiment with a two level navigation. Please check it out here and let me know what you think!

PS: At this point I broke everything in my development build and I found out I can't really udpate the site incrementally. I'm just going to have to redo the navigation, and basically go back through all the pages to update the templates with a different grid system. While I am doing so I will improve the flow by reorganizing some of the pages. When I'm finally done with that which could take a few weeks, I think I'd like to add the "daily limit" setting to the SRS that many users have asked.
