How close BufExplorer is if it has opened in another tab?

[vitalii-c]

I'm using vim with tabs and vim-session plugin, each project lives in its own separate tab.
If I open :ToggleBufExplorer in some tab and forget to close it, then it is not possible to run it in another tab, so before I am able to open it again I should find the project/tab where it is currently running, sometimes it is annoying.

Probably there is features or possibility implement behaviours:

• which will check that explored closed before leavening tab ( I use gt gT nnn gt )
• or check in which tab it currently running in close it there and open in current tab
