Dark Mode Option

Indeed the vote option has only been there for a year or so, but if we use number of views as a measure it is way down the priority list! Also votes are a way better measure of actual user interest.

It is of benefit and wanted.
The iPad team could include it because they didn’t have 25 years of UI code & icons, built on multiple different UI frameworks to go through and adjust, and then test every single bit of UI on all platforms and multiple operating systems. Instead they were building a new UI from scratch. Also the iPad UI has a considerably smaller number of controls than the desktop UI. And don’t forget, there is not a major project (Qt) on iPad such that it really doesn’t make sense to add colour mode capability to the entire UI, and then rewrite the UI in Qt.
[edit] And how could I forget layout! That has a really extensive UI, and shipping dark mode sketchup without dark mode layout would probably not be well received by regular layout users…
