- Aligns artboards to a grid with
100pxgutters - Renames the artboards based on column (number) and row (letter) [
A00,A01,B00,B01,B02] - Organizes the artboards in the layers list by row and column.
Notes: Align expects that artboards that are meant to be in the same row are top aligned on the same Y-axis value. It doesn't care about the X-axis value.
There's a slightly hidden feature that I use a lot but is hard to describe. If you place an artboard in between two rows on the Y-axis and run Align, it will create room for a new row by shifting existing rows down by one, and then will rename accordingly. Imagine you have Artboard 1 that is 10x10 at Y = 1, and Artboard 2 that is 10x10 at Y = 111. If you place a third artboard where 1 < Y < 111, Align will do the rest of the heavy lifting for you.

Aligns artboard to the same grid, but does not rename the artboards. Use this if you don't want your artboard names messed with. Align and Rename does its best to preserve custom artboard names, but sometimes you might not want it.
Allows you to specify a custom name for all artboards. If you have Column and Row indicators (ex: A00), these will be preserved.
If you'd like to remove the custom naming from all artboards, just leave the input field empty.
