If you can wait another 4 or 5 MONTHS, I have it on good authority that "Designer Pro X hiDPI version is planned to be released aprox. in March 2021."
Why ON EARTH they are making us wait until March next year, when self-evidently the HiDPI user interface has already been written is anybody's guess. GADS!

Meanwhile, I have been compelled to start using Affinity Designer, which has more sensible defaults and does a number of much more sensible things.
e.g. A line with an arrow head terminates at the at the point of the arrow! And it's Corner Tool is a joy to behold.

However I have to say that it does have a bit of a learning curve and a pedantic feel to it.
e.g. It seems to be impossible to rotate a group of shapes without rotating the entire Art Board.
