<h4>We get a lot of feature requests, here's the list of them!</h4>
<p class="text-justify">
The requests that come in on Github usually have a good argumentation and a lot of these ideas have made it into vis! To keep a nice overview of them, to clean up
our Github issues and to supply a pool of ideas for people to contribute, we have made this list.
<br /><br />
This is by no means an end-of-the-line for your feature, but just something that we cannot pick up right away or cannot use in our projects at this time.
We'd like to invite people who want to contribute to pick up one (or more!) of these features.
</p>
Legend:
<ul>
<li class="blue">Feature being worked on by us.</li>
<li class="">Feature we might pick up with future releases, but feel free to pick it up for us!</li>
<li class="green">Feature being worked on by the community, link to their forked version.</li>
<li class="pink">Not likely to be picked up by us soon but would be great if the community would add this.</li>
<li class="orange">Feature needing major overhauling of the current framework, not planned soon and unlikely to be picked up by community.</li>
<li class="notyet">Feature that would be easier to create after a large (and planned) refactor.</li>
<li class="done">Implemented and released.</li>

<ul>
<li class="normal">(<a href="https://github.com/almende/vis/issues/308" target="_blank">308</a>) Add a click-to-scroll option similar to click-to-use but it should allow dragging all the time, only block the scrolling without activating it.</li>
<li class="pink">(<a href="https://github.com/almende/vis/issues/207" target="_blank">207</a>) If possible, add Nuget Package support without ruining the current build tools.</li>
