Thank you very much Taifun for your time/effort in selecting for me these extensions.
As a curiosity... Last night I did some cleaning on my desktops (as usual I have thousands of Chrome tabs opened usually >20GB of ocuped RAM)... I think that I closed over 100 instances with "Pura Vida Apps" as the title. Your effort on Pura Vida Apps is worthy of praise.
Another thank you, and of course, I will try all the extensions you recommend.
