Of course I'm using groups. As you can see in the attached file. I have over 600 of them. And I have lost few hours, while working on this periodic table, only for scrolling the groups list and clicking them to open/close. :D
I'm not talking about the feature for most users. If they don't want to, they don't have to tag layers. But when someone is working on some big, complicated project with lots of layers, he can save a lot of time and finger joints by tagging his layers and searching them. ;)
And there is a lot of such projects. Take the web design for example. Sometimes you have to design 20 pages (each one with hundreds of layers) just for one screen size. Multiple that by 3 for other devices and you end up with document consisting of two thousands layers at least. Lots of this layers are similar, and when you have to make a change, with the option to search the layers and change them all at once you can save few hours of your life. :)
As we all know, Affinity seeks to serve UI designers. This option may be their salvation. :)
Oh, and as we speak about UI designers. We have spot colours now. I would love to have "spot" fonts, border thickness and all the things that don't go under 'styles'. :)
And copying and pasting slices in export persona. This one is a must do. Imagine if I want to save each element in the periodic table as a slice. I have to draw every f*ing rectangle by hand. Instead of drawing just the first one and then pressing ctrl+j (or pressing alt and draging) and just changing the position. 118 identical rectangles. Who have enough life for this? :D
I think Affinity needs to get some programmers to design some functionalities. Programmers think differently than designers, and when it comes to designing user interfaces and technical stuff, contributions of programmers can be very helpful. ;)
