A lightweight desktop app for merging .po translation files across culture-specific folders, streamlining localization workflows for Unreal Engine and other multi-language projects.

1. Select Folder: Click the "Select Folder" button to choose the root localization folder containing culture folders (e.g., en-US, fr-FR).

2. Start Merging: After selecting, the app will automatically merge .po files inside each culture folder.

3. Track Progress: The progress bar and status label display the merging status for each folder.

4. Completion: Once finished, a pop-up will confirm that all .po files have been merged successfully.

Each culture folder will now contain a merged.po file with consolidated translations by default. However, if you select the Custom Output Path option, all merged .po files will be saved in a single output folder, with each file prefixed by its culture code (e.g., en-US_merged.po, fr-FR_merged.po).

• Python 3.6+: Required to build or modify the app.
• polib: A Python library for working with .po files. Install via pip:

  pip install polib
