I started this thread almost a year ago. The fact that it is still active means that the topic is still current and the problem is not solved. Leaving aside the quality of the clipped content, the DT users cannot clip pages behind the paywall/login. Nothing changed with DT 3.x.
I do not understand the arguments of the DT team as ... and also note sites with logins or paywalls can be implemented in a way that makes them difficult to clip from .... What does the browser content conversion have in common with the implementation of the login or paywall mechanism? When I am going to capture a page content, I am already logged in, and the login mechanism is therefore not relevant. All I need is to convert the content between the <body> and </body> tags (e.g. the DOM existing in my browser) into the markdown code and to save the result in DT. Evernote can do it, and Quiver can do it, One Note can do it, many other programs can do it. Not just DT. You don’t need to think up the wheel again. Just look at open source projects. For example, Mercury parser extracts only essential HTML code from the page, and Turndown then converts it to markdown. All pure JavaScript. That’s how the competitors work.
