CSS adjustments

Some of the things I noticed, and notes from Janek to make it more user-friendly:

• the logo should be in the left corner (as this is the place users notice first). preferably when clicked to open the 'start' page
• it would be better to have another element (accordion) for revealing additional things. we currently use buttons to reveal them, and buttons suggest action, so they are for different purposes.
• could we have two color options for the buttons? they catch attention a lot, and some of them are not that important. eq. dark violet for important buttons, and a lighter version for less important ones.
• can we change the color of the tabs? grey suggests inactive elements and that's not intuitive.
• can we not use capital letters in buttons? there may be too aggressive.
• can we add 'wait' under the moving logo when loading elements? it may be confusing to users what's going on and they may not get the message
• there should be info to wait when downloading the zipped folder of UC plots. right now we push the button and don't know what is doing on. (I know that the plots are being prepared but the user doesn't).
• nested navbarMenu as defined in re-organising UI #113

to be continued.

The accordion element is the priority task from this issue, once you are finished with tooltips :)
