Editing large amounts of blocks on a screen, as well as revisiting sources from older applications is always a challenge, to find yourself among the blocks.
And if we could leave notes in text, in the creator, to make it easier to find groups of blocks related to certain functionalities of the application. Ideally, it would be possible to move directly to these points, based on a search.
And if the fonts were fixed in size, they would not change with the editor zoom. Thus, it would not interfere when zooming in too much, and it would be very visible even when zooming out.
If a fixed size is not possible, it should be large to be very visual when zooming out.
