If you want to add assemblies to E# for whatever reason, like adding assemblies via clicking links is broken, here's how:
Step 1: Go to E# window and click on 'Install New Assembly'
Step 2: Go to the assembly database, and copy the Github URL of your desired assembly.
Step 3: Paste the URL into E# window and click Next
Notice: if the Github URL you copy is something like: https:// github.com/DaPipex/Ensage/tree/master/HotKeyChanger
you need to remove everything but the last two names, like this
https://github.com/DaPipex/Ensage/tree/master/HotKeyChanger <--- this will NOT work
https://github.com/DaPipex/Ensage <--- this will work
