Lightroom Classic Crop Straighten Tool Cannot Zoom for Precise Alignment

Lightroom classic has a great tool in its tools. I haven’t seen this in paintbrush or other programs - thanks to the developers of this company for such possibilities. Image can rotate! There is even a ruler tool when you click on the strainghter tool, and then! You drive on a line that should be straight and the program perfectly! accurately rotates the image.
Please excuse me, but if such a straight line of small size, but very clear, and other straight lines in the image may not be, then it is very difficult to draw a line correctly, because the image in framing mode can not be enlarged. This is not possible, as I understood, because of the philosophy of the company Adobe (Adobe Company is an industrial brand), where developers know exactly what I need and how I should be better. No small role is played by a user group that accurately assesses the important points to be corrected or changed.
Do I understand correctly the fact that for accurate measurement I just need to send such an image to Photoshop, enlarge there the image in the area where there is a straight line, and measure the angle of inclination with a ruler. Copy such a note, return to Adobe (c) Lightroom and set this angle in the image rotation tool?
And I also really like how the program displays raw files)) People for some reason use strict development programs (rpp, etc.). So I understand - it is already from nothing to do. People who do not want to earn money. But it is already - I just distracted from the question.
