Gemini
Sharing
With each of your saved conversation, you can click on More Options, and select "Share" to get a link that you can send the conversation to. These links are available for as long as the conversation exists, which makes it not a great long term solution if you're planning on having a lot of saved conversations. To manage that, I recommend saving the conversation to Google Drive as a Google Doc. That option does appear to be a desktop only feature as the mobile option only offers validation and a copy to clipboard where save to Google Drive would be.
Clean up
With each of your saved conversation, you can click on More Options, and select "Delete" to remove the conversation. I found that it is more efficient to delete from a mobile device. There, you can long press and click "Delete".
Gemini Advanced Perks
Gemini has two models, a "Fast" and "Thinking". On the "Fast" model, you have unlimited requests. On the "Thinking" model, you get 5 on the free tier. On the Gemini Advanced tier, you get 100 requests. You also get additional Deep Research requests, and access to Veo.
Gemini Advanced also gives you an extension on the number of resources you can have on NotebookLM, 300 instead of 50.
