En Croissant: The Ultimate Chess Toolkit

<Comment deleted by user>
En Croissant in Mac isn't showing the board. Everything works correctly but the board simply isn't visible. Neither are the pieces. Could you look into this please?
If the fritz/chessbase piece set could be added to en-croissant, it'd really help me!
It would be helpful for training games to have different strenght engines available, each with 200 Elo point increments.

Is it possible to adjust an engine’s ELO, and then import the adjusted engine, and do this for every 200 Elo point increment from 2000 - 3400?
Hybrid, specialized and generalized chess engines : When it comes to chess engines, I prefer a diverse pool of engines, that each can help produce solutions that the others could not. It's like being specialized in knowledge and perspectives. The more we learn the better we become. Pretending we are dumber, is not possible. Neither is it for an engine. Downgrading it is not the same thing as being truly rated at a level. There are many chess engine styles and ratings. Finding the unique ones for our needs is not an easy choice.

I assume for many, that are using engines like Stockfish and Lc0 like their combined brute force with heuristics effects, and it's their easy approach to getting skilled rated levels. I prefer using the engines that lucas chess has in their software. I'm not an expert in the field of engine choices. So I rely on other sources to pick my engines.

Chess engine similarities: I would prefer to pick chess engines that are not similar and have different rating levels. The best move will not be the same between engines, but they will all be performing at their best. They will not be blundering or making errors on purpose.

A rating value for an engine can be different depending on there version or where it was rated.

You can always pick a known engine by it's elo progress to fit each rating need from 2000 to 3400.
One factor that needs to be remembered is an engine rating changes depending on the hardware it's used on. An engine that was weak in the past, might be stronger in today's computers.
