Being on i(Pad)OS most of the time, I miss things like Alfred and LaunchBar. Anything that allows me to filter and invoke actionable items via the smallest number of key presses possible makes me happy.
Maybe all you need to do is tweak your action groups, as per Greg’s suggestion above. Problem for me is that I’ve got a lot of actions in a number of groups, accumulated over years of using Drafts. I could (should?) review and prune my actions groups more often. In the meantime, I use this: (https://actions.getdrafts.com/a/1c7).
All this one does is open the actions panel, placing the cursor in the search field ready for you to type the first few letters of the action you’re thinking of, in order to filter the list. I keep this on my primary action bar (the row of extended keys) so it’s always available. If you use an external keyboard and you’re familiar with “slash” commands, I’ve mapped the shortcut to command+/.
Added bonus? Filtering the actions list like this sometimes reminds me of actions I’d completely forgotten about or haven’t used for a while. So it supports the effort of tidying things up even while speeding up access. Win win.
