Hello SubXPlayer Team,Thank you for creating such a great app. It has become one of my favorite tools for language learning.I have two suggestions:* Please remember the selected second translation language for all videos, so I don’t have to choose my native language every time.* On my iPhone 16, the second translated subtitles disappear after I pause and resume a video. It would be great if this setting stayed enabled until I turn it off.These small improvements would make the app even better. Thank you!

Developer Response
Geri bildiriminiz için teşekkürler! Haklısınız, iPhone 17 Pro gibi güçlü bir cihazda bu tarz bir takılma olmamalı.Çift altyazılı oynatma sırasında bazı video formatlarında telefon arka planda fazla yoruluyor, bu da hem takılmaya hem ısınmaya yol açıyor. Sorunun kaynağını biliyorum ve oynatma motorunda performansı ciddi şekilde artıracak bir güncelleme üzerinde çalışıyorum. Bu, kapsamlı bir alt yapı değişikliği olduğu için test sürecine zaman ayırıyorum, ama önceliğim bu sorunu çözmek.Sabrınız için teşekkürler, gelişmeleri uygulama güncellemeleriyle paylaşacağım!
• New: Boost volume up to 200%
• Fixed: Subtitle navigation bugs when setting a delay
• Performance and stability improvements
