5 sugestions

[thiagaum]

1- locker for workspace [it will not allow to missclick and resize or take of the position - it occour a lot wih my secondary view when im drawing];
2- match zoom and pan: primary x secondary view [imagine that i use an image from referece to draw and put that on my secondary view, now imagine if i can lock that reference and everytime i zoom pan rotate invert my draw, my secondary view does the same. To be fair i only saw that feature on photoshop];
3- gridlines/ruler;
4-opacity control for layerstacks [control opacity of all layer stacked at once];
5- ESQ to quit selection [i spend 1 hour to understand how to diselect ¬¬, just put that on "esq"]

Hi!
I add your suggestions. Thank you

To adjust the opacity of multiple layers at once in Black Ink, follow these steps:
- Make a group selection: Select the layers you want to modify together.
- Use the "Layer Operator Properties" panel: In this panel, you can adjust the opacity for all the selected layers simultaneously.

For more details, check out the documentation:
