Hello! I would like to add a request for support of phonetic guide text. Phonetic guides are usually small characters directly above/below main content (or beside in the case of vertical text), which show how a word is pronounced. Phonetic guides are frequently used in East Asian languages where characters may have multiple pronunciations. Attached is an example showing phonetic guide text in a news article in Japanese.
Some other names for these guides are "furigana", which is specific to Japanese, and "ruby text" or "ruby characters" (ルビ, 루비, etc), which is another name for these guides (https://en.wikipedia.org/wiki/Ruby_character).
For reference to other implementations of phonetic guide text, in HTML5, they can be produced with the `ruby` tag (https://developer.mozilla.org/en-US/docs/Web/HTML/Element/ruby). Most major word editors support phonetic guides as well, such as Microsoft Word (https://support.microsoft.com/en-us/office/add-phonetic-guides-to-east-asian-text-c03ad8e4-799b-499e-89a2-c749fc5397e8) and Apple Pages (https://support.apple.com/guide/pages/use-phonetic-guides-tana3a61f9d3/mac).
Currently, the workaround in Affinity seems to be manually positioning smaller text boxes alongside the primary ones. However, this quickly becomes impractical, especially when the text content changes and all phonetic guides need to be rearranged. I think this feature and vertical text (https://forum.affinity.serif.com/index.php?/topic/68887-japanese-vertical-text/) would go a long way toward making Affinity available for use in applications using East Asian languages. I should note, there was a discussion about "furigana" in a previous thread (https://forum.affinity.serif.com/index.php?/topic/40881-japanese-furigana-ruby-ルビ/#comment-204976), but it was not in the feature request section, so I felt it might be better to move it here as well as provide additional details.
Thank you for your time!
