I have a few community plugins enabled in my Obsidian. One of them is “Paste URL into selection” - and it fits very well into the Markdown workflow. Also what you might know from other tools like Slack.
My Obsidian vault is “all-in-one”, personally I don’t like switching between multiple vaults for work and private stuff, and I organize it in a way to keep things separated in one vault. Multiple templates I’m using automatically generate Tasks in my vault, therefore I need a convenient way to see open work tasks. This blog posting describes the approach I’m using.
One of the cool features it has is named “Daily Notes”. As the name implies, there is a new note generated for every day. For me, this is used for writing down notes which do not deserve their own note. But also this is rather heavily used to share all kind of content from my mobile devides into the daily note in the first place. Content doesn’t have to stay there, in fact most of it is either handled one way or another, or is moved to a different place. But it is a very nice collection point in the first place.
For syncing files between my devices I’m using SyncThing. This tool is reliable, available on Linux, Android, Mac and iOS. And it encrypts the communication.
