I would like to suggest a change to how searches are displayed in the sidebar.
I use taskpaper in half of my 13" laptop screen, with a different app in the other half.
This means that the sidebar is somewhat width-constrained - yes, I can increase the sidebar’s width but, then, my writing area feels too narrow.
The way in which the suggested search is displayed takes up a lot of sidebar width:
@search(tasks not @done)
… and this means that, in my relatively common setup, the most important part of the phrase (the part that identifies what it does) is partially hidden. At the default width, I can see only this much:
If the cog icon was replaced with a search icon, that indicator would allow you to drop the “@search(…)” chrome and display the entire actual search phrase:
tasks not @done
… we not only get to see that it is a search, we also get to see more of what the actual search is.
