Great! Thank you!
I’m not an English native speaker, so I must have misunderstood this sentence:
What makes things difficult is that you want to align something vertical in the middle of the text on the first line.
I’m not sure that I want to align something in the middle of the of the text on the first line. The only thing I want from the first line is to stick to the left.
When there is no 2-line expressions everything is good:
But when there are 2(or more)-line expressions, than I want the alignment to be generally the same as in the pic above, but align the second/third/… lines of this long expression not to the left but to the first = of the first line of this long expression.
Just thought I’d clarify it just in case, so you can make sure you understand my intentions correctly. I’m pretty sure you’ve come up with the best solution possible.
