Description

• Replace "Ask for Save Folder" toggle with a dropdown allowing to chose a new option: copy to clipboard

Screenshots

After:

Testing

Copy to Clipboard:

1. Select "Screenshot Mode: Copy to Clipboard"
2. Verify that only all screenshot options are either invisible or removed
3. Verify that the screenshot button in the player is present
4. Verify that clicking on the screenshot button copy the screenshot to clipboard and does not save on disk

Desktop

• OS: Bazzite (Fedora based Linux distro)
• OS Version: 43
• FreeTube version: 0.24.0

Additional context

• I'm not really satisfied of the "both" option, not really future proof if more modes are added. It could be two toggles, but again not really sure what the UI would look likle with more modes. Let me know what you think.
• Electron Clipboard API only supports JPEG and PNG but from my tests it seems that ultimately the image ends up as PNG anyways
• This feature is breaking backward compatibility as the "enable screenshot" option is gone. Not sure if there are migrations code or if retrocoompatibility should be kept no matter what.

I'm new to this project so I still have a bit to learn about!

Please use the standard web navigator.clipboard API, like we do for copying text, rather than going to the main process and using the Electron specific APIs. Copying to the clipboard should be possible in FreeTubeAndroid too just like prompting for a save location (only the save to default folder is electron only).

I agree with you that "both" is odd, please remove it. Additionally rather than replacing the enable screenshot switch it would be better if you replaced the prompt for save location one. That dropdown would still default to prompting for the save location, in Electron builds it should have 3 options (the two existing ones plus copying to the clipboard) outside of Electron e.g. in FreeTubeAndroid it should only have prompting for the save location or copying to the clipboard.

As you already discovered it only makes sense to write PNGs to the clipboard, that id because images sit on the clipboard in operating system specific bitmap formats, not PNGs or JPEGs, so writing a PNG avoids losing details that would be lost in the lossy conversion to JPEG. As copying to the clipboard will always use PNG, the format and quality options should be hidden or at least disabled when the clipboard option is selected.

Testing an actual FreeTubeAndroid build is a bit more involved, so you can check the settings UI outside of Electron with pnpm run dev:web, that is unusable for most things as FreeTube cannot fetch information from YouTube in a normal web browser but for "offline" stuff like the settings page it should work fine.
