Recently, I have been inspired by many complaining about GG, and have thus built a [beta] version of a GG to TW converter. While still full of bugs and in need of much more work and polishing, you can still get a gist of how it will work when fully completed.
What I will be adding: For those of you that have tested, you can see that the text of the tiddler includes needless strings such as "Forward", "Reply", and more from the text-grabbing from GG: I will fix this soon when I have time. In addition to this, I have just thrown together the UI in 5 minutes, so it will be upgraded, too.
Furthermore, it will soon be able to handle larger downloads, and a way for you to select which page you would like to get it from.
Note for those running it locally bc of download: The API in use to bypass CORS is quite finicky, and will throw an error. To fix this (only needed if downloaded and not run via given subdomain) , just clear all your browser history and cache: The API will reset the CORS access Header.
I would appreciate to hear some of your questions, comments, and concerns, and I will answer them ASAP. Feel free to Star, Fork, Download, or Open an Issue at the project's GitHub:
