TD-RED

I worked with Illustrator for many years. Aff. Designer is a great alternative and I switched from Adobe to Affinity Designer & Photo. But obviously the following important functions are missing: 1. fill closed areas in illustrations with an interactive paint bucket without creating surfaces beforehand. 2. A line or curve is selected. The function to select all curves and lines that have the same contour color or line width, for example, is now missing. Is there a solution here I don't know yet?
