Add configuration for vertical height of Open Editor tabs

[matt-kempster]

I love using "Open Editors" as a de facto "vertical tabs" feature. In fact, I fully disable regular horizontal tabs because I find them largely useless. However, there is one downside of managing tabs this way: vertical space.

In this screenshot, you can see how small these Open Editor tabs are:

I would love to be able to configure the vertical height of each. I'd add a couple pixels to the standard height to make each tab a bit taller, thus easier to click.

Thank you!

This is a fair feature request, however we do not have it on our immediate plan. Thus assigning to backlog for now. Thanks

Though it might be seen as a duplicate of make the workbench font customisable
