Dear @Dominic and @walt.farrell
Thank you for your quick responses. I wasn't expecting to be able to group artboards. That does the trick for distributing artboards. But I sometimes need to redistribute all the artboards. Let's say I start working on the project with 5 rows and suddenly I need to see the project in 6 rows. Then I need to redistribute all the artboards because the artboard names are unique to each design. With this solution, I will have to group every 6 artboards and redistribute them. The problem is that each 6 artboards are now in two rows. So the artboards will be mixed up. Let's say it was going like 1,2,3,4,5 This time it will be like 1,4,3,6,5,2. And there are 500 artboards.
I found another missing feature while testing. I can't see artboard bounds when I place them in another artboard. Let's say I have 100x100 canvas and a 70x70 canvas in it. I have to press the Outline View Mode button every time I need to see the artboard. There must be a view mode that shows canvas bounds.
The third missing thing is artboard names of the old illustrator files. I hope the developers team can solve it. I have thousands of valuable illustrator files that contain very important artboard names. And I don't want to keep adobe programs on my computer.
After spotting the missing things I realized that each artboard has its own x,y attributes when I copy paste my designs to an other software. Also each artboard has its own grids. This is a big plus for Affinity
@Pšenda Artboards are life-saving when you need to do a Font design that includes multiple vector elements which have to be exported afterward. While you work on the project, you desire to see the whole objects and the entire process aligned into grids before you start on the project.
