I need to do some settings but it is not possible.

One thing I liked about Chess.com is that we could see what opening we are playing when in game. That is not possible on Lichess. I installed Lichess Tools browser extension by Siderite, but that only shows it in analysis. I learned and memorized so many openings back when I was playing on Chess.com, and I am forgetting the names of all of them. Is it possible to achieve this?

But the bigger problem is analysis. First of all, real time engine on the cloud is not possible, it runs locally, and I can totally understand that given that Lichess is a non-profit organization and they don't have powerful servers. So I wanted to ask that if there is any other service on a 3rd party site which can offer real time engine evaluation running on the cloud? And is there a reliable way to import my current game from Lichess over to it?

Okay, but the problem with Lichess is that unlike Chess.com, it doesn't show the engine lines, even when running locally. If the engine is running on my system, let me at least see what it's thinking, besides the 1 or 2 lines that get drawn on the board, which actually, is another of my problem, because, I don't know if I did something (I tired disabling Lichess Tools also), or if Lichess did it, but I am no longer getting those lines drawn on the board which shows what the best move is according to the engine, and it is really frustrating as I can only see the Stockfish evaluation but don't know what the best move is. But the lines drawn from the computer analysis draw just fine.

Click on the gear symbol to configure the number of engine lines up to the top five.

With the rest I can't help.

@lonelypeanut Oh my bad, I set the number of lines to 0, that is why I wasn't getting any lines drawn. Thanks for noting that out.

I don't understand how would it be supposed to help. I can't imagine that someone has no idea what to play after 1. e4 e5 2. Nf3 Nc6 3. d4 but once you tell them it's called Scotch, they sudenly know what to do.

Lichess lets you run a server side (cloud, whatever) analysis of your game once it's finished. There is a big button "Request computer analysis" right below the board when you switch to analysis mode. The only case where you only have local engine analysis is when you want to investigate the unplayed sidelines (except those suggested by engine instead of moves marked as blunders/mistakes/inaccuracies).

Already answered in comment #2.

IIRC it can be enabled/disabled somewhere under the "hamburger icon" menu and there may be even a keyboard shortcut for it, maybe you pressed it accidentally.
