Along with the missing registration of TStyleTag, the following components cannot be used in styles without hand editing FMX or Style files.
I’ve updated the package to now register these missing style components so you can use them in custom styles.
The change is straight forward if you have already downloaded and installed the previous package.
The register procedure should now look something like this:
RegisterComponents('Shapes', [TStyleTag, TFontObject, TBrushObject]);
NOTE: You may want to register them to a different palette location.
