If I could use CSS (and especially CSS Grid) (or something just as straightforward and easy to use*) in Lazarus UI development (for both local and remote GUIs), Lazarus would become compelling for me to start using.
Until then, I'll just stick to straight FPC and no Lazarus for development work.
*I'd prefer it just be CSS/CSS-Grid though, as those are already well documented and there are plenty of examples on how to use them.
