Excellent improvement that has been introduced with 1.3.0.3, which beside a more modern look and streamlined experience, specifically addresses readability issues when working with a high pixel density.
Amazing to see that for the finishing touch as well 
The Navigator is a fundamental part of Cwicly which can make life so easy under specific conditions. Now it does, without any doubt.
By far the most superior UI/UX I’ve ever seen in any tool.
No complaints left; I appreciate you for always having an open ear to the community.
Just a little thought, which could be handy, especially for inexperienced users or clients → displaying the block type in a popover while hovering over the block icon in the Navigator.
When giving the block a custom name/label, the only descriptive fallback (Navigator or Block Inspector) is the randomly generated block class/ID name - if not changed.
PS: Sorry for being so annoying on this topic, it’s just such an important part.
