You can try the plugin "Preview the collapsed list". Maybe this helps until the requested feature is implemented.

If you use the plugin "browserTab", opening a new tab with ctrl+t opens a blank tab. I hope that this workaround is helpful!

I have the same question. Is there any news on using the inbox feature with e.g. WhatsApp or Telegram or email? Or did anyone set it up with other apps? It would be such a great feature to collect content, in particular on mobile (since no native sharing feature is available to date).
