Do you have a resource you like for "advanced" Alfred use?
No, not that I can think of. The app comes pre-loaded with a bunch of templates you can insert. I mostly just started from the templates and substituted my own perl or python scripts for things.
I deal with a huge number of different projects at work, for example. I have a workflow that imports the master excel spreadsheet and builds an instantly searchable database of every project, with links to all relevant portals and information. I can just start typing a project name or number (or other relevant info) and instantly jump to the project’s Sharepoint page, my local files directory, emails about that project, the publicly-accessible portal for it, etc etc. I use it constantly every day.
I also use Alfred to search industry-specific search engines, to draft repetitive emails for me, and to file things away. I have many little conveniences set up, like a workflow that configures various laptop settings based on location (printers, audio devices, volume level, etc).
Honestly if I had to choose between “Mac OS with no Alfred” and “Windows with Alfred,” I’d stick with Alfred. It’s such a helpful app.
