We have no way to get the tag when inheriting Timber.Tree, because it's marked as internal/package-private for consumers https://github.com/JakeWharton/timber/blob/dc45d69b081a03e3fb83e81a7aee0f430f46b4f1/timber/src/main/java/timber/log/Timber.kt#L22. This means, when timber is used like this:

Timber.tag("Tag")
Timber.e("Issue")

the tag will not be reflected on Sentry.

If this gets traction, we could either offer a reflection-based support or automatically infer classname of the caller (that's what Timber.DebugTree does by default).

Please, vote on this issue if you'd like us to provide support for Timber tags.
