--- Comment #4 from ezh <eugene.savit...@gmail.com> --- I'm trying to move to Linux from Windows, but still can't, one of it is this small but annoying problem. :( My second monitor is in portrait mode, so there is plenty of vertical space and since I use many programs on this monitor I set it for for two-row taskbar. Windows has only "group by row" preset. And for me the "by column" is bad, since, as I have explained in the first bug comment: looking by a line for a same program second and more window is quicker, than you have to move your eyes zigzag. I set the taskbar for two-row myself, so it is not a problem that there is a free space. On the second screen I have: 1. Two Firefox Developer edition: 1 x Google Docs and 1 x Yandex music 2. Telegram 3. Skype 4. Thunderbird windows + 3-4 open and not sent e-mail windows 5. Some LibreOffice docs & sheets I got by e-mail (for personal I use Google Docs) 6. Some pdfs I got by e-mail -- You are receiving this mail because: You are watching all bug changes.
