The persistent alignment controls in Sketch could double as a way to add guides around canvas selections. The basic idea is that depressing a modifier key would switch the toolbar into a guide placement quasi-mode, with the icons and tooltips updating to reflect the change. Ideally, the icons in the toolbar would reflect the guide color set in Sketch’s preferences (red being the default).
A few ideas to improve the alignment guides in Bohemian Coding’s Sketch, which I’ve been using more and more since Adobe announced that they pulled the plug on Fireworks — just like Obama will do to your sweet old granny.
In the current version (2.3.1), guide positions are hard to read and you can’t easily space them from each other and the edge of the artboard.
There is also currently no way to position them by numeric input, a feature I found very useful in Fireworks.
Say you’ve decided to change the height (or width) of an element in your design, a change that must propagate. It would be great to be able to move all of the guides on one axis in one pass.
The input boxes for individual and batch position adjustment would of course let you increment their values using the arrow keys and change them using mathematical operations, two features I’ve found really useful in Sketch.
