i added support for two more mods. i was too lazy to create another pull request, so here is the files.zip :D

the [ETF] Entity Texture Features button can be found in the Resource Packs menu, and the Server Country Flags button can be found in the Multiplayer menu.

Thank you for your contribution,
The mod "[ETF] Entity Texture Features" is already supported, but I see that the folder name has been changed.
Your changes will be taken into account in the next update.
