Improving internal and external links

[apayne97]

Several times now I have been looking for something I know is on the website but just can't seem to find it - for instance, I just wanted to download a video showing a DESRES trajectory but just kept going in circles clicking on links that led nowhere.

One concrete suggestion is to have a constantly visible legend for the different labels telling me where I will go when I click on it (i.e. a "proteins" page, an external link, etc)

Additionally, if there could be some way to orient the user in "space" in the website, i.e. by highlighting the panel you're in and showing how far down the page you are (maybe not possible with a static site? idk)
