Project: QGIS
Version: 3.10 LTR
In QGIS 3.10 we've finally implemented a long-awaited feature, allowing users to manage their own libraries of custom text formats and label settings alongside their existing symbol libraries!
Now, the Style Manager dialog can be used to manage text formats (which store the font, color, buffers, shadows, and backgrounds of text formats) and layer-wide label settings. (A "text format" includes just font settings and other appearance related settings, while a "labe setting" also includes layer-type specific settings such as label placement, priority, and rendering settings).
Text Formats and Label Settings offer all the same functionality as you're used to for managing symbols and color ramps within styles, including import and export to XML files, tagging, smart groups, favoriting etc...
