[ ] 1. I'm currently translating this app to Russian and noticed the implementation of plurals being wrong. https://github.com/Raival-e/File-Explorer-Compose/blob/42cb075acf23233bc1f4be098d00bdd135e5ed1c/app/src/main/res/values/strings.xml#L137-L139 While it can work in English, it's not the case for other languages.
