🔗 Linked issue

Resolves #2518

📚 Description

• Reworked the title bar such that the links above direct to sites that might be of interest (Docs, Forums, GitHub, etc.).
• Removed some code that did not seem necessary for now like user profiles and the search bar (might add it back though should it become necessary) Readded these functionalities back
• Some dropdown menus to the nav bar that shows some other links that users might find interesting (to Docs and Forums)
• Add collapsible functionality to the title bar so that it is mobile responsive

Not really quite necessary, just a nice to have that could aid people going to the site in navigating to other places.

Thanks!

Removed some code that did not seem necessary for now like user profiles and the search bar (might add it back though should it become necessary)

These are not shown on the main start page, but once you login they are shown (try the subpath /dashboard - but this section is a bit broken currently). So please don't remove these parts / readd them.

I don't think the nightly builds are that relevant.

[plvzfq-rit]

Ah, I'll remove them then, much thanks+

[plvzfq-rit]

I'll readd the functionalities back as soon as I could; apologies for that;;;

[plvzfq-rit]

Readded the functionalities and changed out the nightly build with Gitter to partially help with issue #2562. Also made some of the menus dropdowns so that one could go farther.
