Thank you for the feedback and for asking the question. Yes, a big part of the Darq Side membership is a growing collection of 2K- and 4K-friendly components. As of today we have 47 Large (2K) and 38 X-Large (4K) components, with another 4 of each size to be published in a couple of days. I wish I could offer everything with the free DarqUI version but some of the more complex windows take literally days to upsize, almost all of it by hand. But on the plus side the process has gotten a lot faster than it was a few months ago.
There are also a bunch of improvements, conveniences and automations built into in the patron-enabled UI that the members seem to be pretty happy with. One example: an "auto-seek" feature was added recently that automatically tab-targets and stops on your choice of NPCs, harvestables, etc. A few of the 2K/4K pieces are shown below. You should be able to download a sample 4K Broker file on the front page of the Darq Side, although the "official" 4K Broker has been refined considerably since that was published. I invite you to take a look
-- a Legendary membership works out to about 10 cents per day, and even though I'm probably a little bit biased I think it's a pretty good value.
