Fixed the UX so that they look alike. The reason they were different is that the Web can show more than one line if you are not on localhost, like on your phone for instance. Since there can be many lines the evalution marker was set for every line. In the Pico analysis coming from the picochess backend there can only be one line at the moment, so the eval was one step higher to give more space for the line.
But I agree, this is now better UX, so I updated it.
The "E" means the chosen engine, but its not redundant. If you have tutor activated, and are in a move entering mode like Hint On, or Eval, then the tutor will be sending the evaluation lines, and then its marked with a "T". When you play against an engine and you have tutor activated, you will see that its "T" when its your turn and tutor is running, and "E" when the engine is thinking and the chosen engine sends the analyses.
