I have been using KM for around a year or so and remember I looked at both KM and BTT (and Alfred Packs) to decide what I wanted to use. I found this helpful in getting a better understanding.
My main usage of KM today is:
text snippets (e.g. see here), date snippets, question snippets, shortcuts for smilies > primarily for email communication and slack, etc
window management > i.e. open devonthink and browser in this and that setup on the monitor
management of specific programmes like Devonthink, iThoughts, iTunes, etc which are not always easy to navigate with my own palettes and/or shortcuts. Specifically for DT I do use a pretty big palette which I created for myself.
markdown shortcuts to create all types of markdown syntax when creating notes in md
bluetooth management while connecting various devices
I also implemented a lot of site bookmarks but tend to use Alfred’s “Web search” for that increasingly (and it is awesome) e.g. when searching on this forum I have an Alfred’s Web search which goes directly into the search menu with the text I am search for. But e.g. have a KM macro which actually opens Alfred’s settings directly for me.
I found this source super helpful as I tried to understand how KM works.
We are aware of the usefulness for people using many favorites or smart groups and rules. However, the implementation, especially regarding the smart rules, has to consider more than merely segregating the items as there can be interplay between them in their order.
Fingers crossed the team will figure it out. With better organization, there is endless potential for automation with smar rules via Devonthink and might position DT yet again in another product category very strongly.
