Este perfect,ceea ce imi trebuia demult.Imi place ca se mareste,micsoreaza si se poate muta acolo unde doresc.
Nice extension but, you can't use it in mobile view, because it's loaded inside the window. That's a big issue.
Awesome! Fixed the Google Tasks problem with the canvas view being obsolete. Thank you! Here's what I did: 1) install this extension: 'Live editor for CSS, Less & Sass - Magic CSS' 2) put this css into the extension's css editor: .gb_gd,.gb_Md,.gb_od,.gb_Zb { display: none; } .brC-brG { width: 100vw!important; } .G4zhSc,.CTxcDf { width: 100%; } Set it to apply automatically (little icon at top of extension's window). To get it to work I need to click on the Extension icon in the address bar to activate it (not sure why), then press F12 to bring up devtools (not sure why either). That's it!
Best plugin for editing CSS styles, also handful LESS and SASS editor. Thank you for great plugin :)
