+Queries are initial queries for selection on fzf, i.e:

+tktl buildah push

+will autoselect the buildah taskrun (or ask to choose if there is multiple) and

+Flags:
+
+-l select the last taskruns
+-f follow logs
+-K use kss for previewing the taskruns (need to be installed)
+-t use tkn to display the logs
+-c choose a specific container (ie step) not supported with -t
