Cannot change font border / stroke to outside (inside only)

Hi @janl31511816, as XD is not going to have any improvements and in support only mode (also having a sunset), I'm not able to suggest you to make a feature request on the official site. But as a workaround, you can clone the letter, make its fill invisible, resize it and apply stroke to the "filless clone" to simulate the inside or outside stroke effect (work very well for stroking outside of the type especially, if you take the clone below of the original type in the layer order without resizing it and increasing the stroke size of that clone below). Hope this gives you an idea!
