Hi,
Love Affinity Designer.
This is an issue when importing SVG files.
In SVG, a common method for centreing text in a box is to use percentage values for X and Y attributes of the <text> element. The same method also uses the "dominant-baseline" attribute. See the small enclosed example to show the technique.
It is unfortunate that SVGs that use these attributes do not currently import into AD correctly (but do import into browsers and Inkscape correctly). The text is not centred in the box at all.

It would be a useful enhancement to support these attributes. Perhaps this one could be quick/fairly easy to resolve, knocking another issue off the list?
