Main Features

Support Incremental Subtitle Search (#91) [Thanks @KRSHH]

Subtitles can now be filtered by incremental search. This is useful when jumping to a specific subtitle.

You can search using CTRL+F or the search button on the sidebar.

Add another LLM translation engine - KoboldCpp, LiteLLM, OpenAI Like (#74 [#80])

Two LLM engines have been added. LiteLLM is a proxy server that allows integration with various LLMs such as Gemini and Grok.

Support Reasoning Models such as Qwen3, DeepSeek for LLM translation

Inference models such as Qwen3 are now supported. Inference messages are now automatically removed.

Subtitle Settings Enhancement (#101)

Subtitles can now be set to a background color to improve visibility.

It is also now possible to have different font settings for primary and secondary.

video\subtitles\video.srt

The default subtitle folder is subs, subtitles. (case-insensitive) Folders can be customized in the settings.

Chinese specific enhancements

Several enhancements have been made for Chinese users.

Support Chinese word segmentation (#84)

You can now select one Chinese word at a time.

Support translation between Simplified and Traditional Chinese (#82)
