FEATURE REQUEST -- Simple Text Tool?

Sometimes I just need to throw some text on a screen as a temporary measure; a lower third, an ADR line, a missing shot, a VFX number, subtitles, those kinds of things -- and most of the time I don't need the heavy firepower of an advanced (and amazing) motion graphics app.  I find that inserting any text into most of my projects, even just a few words in the default font, can bog down my playback performance, which is frustrating.

When I turn the text track off, playback is fine. When I turn it on, it gets choppy.

I know this would be an extremely non-fancy, low-fi tool, but I would LOVE to have an option of a simple text tool as a seperate function of Premiere for these kinds of low-fi needs.  All I need is a few lines, the ability to adjust size and position, a font, color and opacity option -- I don't even need keyframes of any kind!  Just some letters on the screen.

Or if something like this already exists -- please do tell!

Thanks for hearing me out!!
