This is a trivial thing, and pretty much won’t be changed as it throws out what people are now used to, but I wanted to mention it anyway.
With the Align command, the command to align horizontal centres is actually aligning vertical ones and vice versa.
What I mean is a horizontal centre is the centre of an object along the x-axis but parallel to the y-axis. i.e. they have a formula x=c. Vertical centres are a certain distance up the y-axis (y=c). The terminology in this command is the reverse of this.
Ok. Got my gripe out. Been meaning to say something for months but finally got around to it. You may carry on with your lives now.
