In the newest version 15.4.4445 maybe the last also. Since we don't have tabbed windows in Linux yet? (Everything in Linux is TABBED even the file managers) I just open every session to full screen. Up to 20 computers at one time but now I get this annoying thing like a really old version of VirtualBox VM "Sending All Keys Enabled - Sending All Keys disabled"

Just that popping up eveytime I switch computers is annoying. But what is really sending me over the edge is resizing EVERY window. So it's about a half inch off the bottom of my screen. Otherwise I can't use my "Cairo Dock" normally if I put the mouse at the bottom it pops up resizes the open window and click what I need. Now I need to resize EACH window to access the dock. Yes it's not huge but I work on hundreds of computers each month and it's just one more step I don't need to make.
I wanted two things in Linux TABS, TABS, TABS and away to KILL, DISABLE, NEVER SEE STUPID "RECENT CONNECTIONS" EVER AGAIN!!!
So can the new whatever it's for feature be rolled back like it used to work?
Can I turn off "Sending All Keys Enabled"?
Will we ever get tabbed windows in Linux?
(then I would only need to resize ONE window instead of 20 windows)
Thank you for your time.
TV is still the best remote software out there just wish you wouldn't fix it when it's not broken.
