Directly export to Github from a language or a project page
It would be nice if I could automatically export from a language page, or if I could export all to Github from the project page.

To automate the import/export to GitHub, you can use webhooks: https://poeditor.com/help/how_to_use_the_github_webhook
After you set the links between the GitHub language files and the corresponding languages in POEditor, anyone can trigger the updates both ways: to get the terms (and translations) from GitHub and to export the translations in POEditor to the linked file in your repos. -

I agree. I'm working on 4 projects, each project has more that 10 strings files. If I want to use POEditor GitHub integration the GitHub Integration tab will get unusable with 40 more entries.
