I am soooo enjoying the Creality falcon A1C engraver and Creality falcon design space. However a couple of things. 1. withthe ruler ruler its REALLY hard to see the very small sized font and also with any light signing through the enclosure its also makes it hard to see due to the font being coloured light blue. Could you add the feature in the settings to allow you to choose font size and colour a lot of your market has a demographic of older people who dont see these characters the way tou have set them up. 2. If you could give people the option of super imposed a sqaure or shape on the image taken by the A1C camera to indicate areas of no travel for the laser as sometimes we are engraving lower on an object and the laser crashes into the higher section of the part. 3. cant seem to find or operate the ap1 mini air purifier from design space unless i use my phone and when using my phone and also cant control the engraver. Could you create these working options aslo. Regards Luke
