I've been putting off upgrading to 2019 because I have several complicated projects going at once and I am pretty satisfied with 2018 SP5 stability. But - since we're now at 2019 SP4 I'm wondering if there's any new features that are so great and WOW that I should really just stop waiting until SP5 and go ahead and start working in 2019 SP4 because it will make my life so much more awesome-r. 

For comparison I'm thinking of something like:

Great: Selection Breadcrumbs, Configuration Selection Toolbar

Medium: Sketch Colors, Midpoint Line

My current projects are metal fabrication - stairs, sheet metal, welding details, and lots of complicated drawing sheets. I tend to get most frustrated with SW when doing drawings (slow drawings, block issues in detail views, Dimension lines getting lost in section views, etc)

Thanks!
