//
// TODO list for timer plugin
//

// BUG: Some QTimers appear as free timers
// BUG: QTimeLine class name not shown
// BUG: No thread safety yet
//          Related: Protect against timer deletion
// BUG: Sorting in the view doesn't work well
// BUG: Only top-level timers are shown (bug in probe)

// ! Delete old free timers
// ! Wakeup time for QTimers
// ! Add button to view object info
// ! Test timer added/removed at runtime
// Automatic column resizing
// Filter line edit
// Buttons to kill or slow down timer and start timer
// Add clear button that removes all free timers and resets statistics for normal timers
// Add big fat "total wakeups / sec" label to the status bar
// Retrieve receiver name from connection model
//     Add to view as column: receivers: slotXYZ and 3 others (shown in tooltip)
// Move signal hook to probe interface
//     Then maybe add general signal profiler plugin, or even visualization
// Flash delegate when timer triggered
// Color cell in view redish, depending on how active the timer is
