- Very useful extension! Has it a possibility to hide the "200" responses? I want to see only "400" and "500" response codes

- Pretty useful extension. Thanks for developing it. But pls add a language switch in it. The Google-translated texts look pretty much weird :P

- The recent changes with XHR and pro mode, everyone else has voiced their opinions adequately. I've taken to minimising this by clicking the eyeball when I'm not interested in debugging. Even when minimised the clickable hitbox for this extends far out to the left of the eyeball! I would have expected this hitbox to be locked in to the actual eyeball. The micro version in this is not micro enough also. I do not need "filter", "xhr" or "frame". You should be able to filter out what buttons are available in order to make this more micro again.

- It was a great tool for displaying a specific header in a small non intrusive way. However after the recent update the developer has put a time limit on the display, with an annoying "buy"-message instead. The application has, other than the new purchase demand, little to no change at all. Not the way to go about keeping users. Looking for ways to drop a few versions or uninstall completely. I am sad to see it go.

- Leider seit dem letzten Update nur mehr begrenzt brauchbar. Im Micromode verschwinden die Infos nicht mehr nach einer bestimmten Zeit und verhindert klicken von Buttons in der Ecke.

- I liked this extension but the recent pro update made it to annoying to use. Have to find something else now

- I liked this extension very much, but the recent introduced notification "Get the PRO version..." on every display is very annoying. Looking for alternatives or ways to disable this..

- This has been an extremely useful tool in my toolkit for quite a long time but it has recently switched to an outrageously expensive subscription based extension. A modest $1 or $2 one time payment and I would have been fine with paying, but $50 lifetime, $10/year, or $1/month is just FAR too much to ask.

- Good start. It's missing a simple mechanism to switch on/off w/o having visit extensions configuration.
