I often have long conversations with Lumo and weeks or months later need to refer to just a section of that conversation. I know there is a search feature, but I'd like to be able to place a bookmark at a specific point of a conversation instead of conducting a keyword search across all conversations.

For example, I'm using Lumo for development and had some ideas for future features that I can't get to right now, and I need to keep the conversation on track. Six months from now, I'd like to quickly jump back to the part of the conversation that discussed these features.
