Improve options and behavior of new tabs

[Gordo]

3) There is an option “Open new tab from an existing tab in foreground by default”
This is default behavior of Chromium

No, in Chromium, tabs which are opened by middle clicking on link, open in background. Not in foreground. The tab from which new tab was opened, stays active.

As for convenience, current implementation is undeniably flawed, because if in Cent browser the option “New tab position” is set to “Next to current tab” and, for example:
1) tab 5 is currently in foreground
2) user closes tab 10
3) user reopens last closed tab
4) that reopened tab, which was tab 10 before, opens in position of tab 6

This situation is handled correctly in Slimjet and Firefox (and in Chrome and Cent browser with default setting for “New tab position”)

I'm just suggesting, thank you for your time anyway.
