Hi @jh-RLI

• I added input and output icons (I had to create a placeholder for that, so you will probably have to change this)
• Also added an eye icon to the toggle button
• Removed the focus around the toggle button after clicking it (focus for keyboard is still present, of course)
• Did minor styling changes to sidebar
• Since I'm sometimes using Bootstrap icons, I thought it would be necessary to add their MIT license somewhere, that's what I did on the new base-sidebar.html. I guess it's not the best place to add it, but I didn't know to put it. Also, if you think this is not necessary, feel free to remove it
