The default task report (task next) looks a bit bulky in my opinion:

I use the task view popup mostly to get an overview of my tasks, and I find one line per task much more readable. So I configured a slimmer report view in my ~/.taskrc:

report.nextpopup.columns      = id,depends.count,priority,project,tags,due.relative,description.truncated_count,urgency
report.nextpopup.description  = Most urgent tasks, one line each
report.nextpopup.filter       = status:pending limit:page
report.nextpopup.labels       = ID,Deps,P,Project,Tag,Due,Description,Urg
report.nextpopup.sort         = urgency-

With this patch, I can now add cmdline = "nextpopup" (and also some filters if I want) to my task widget setup, and the popup looks much better-arranged:
