Allow NnnExplorer() to not close but go to existing NNNExplorer

[rollf]

Hi,
my workflow is 1) Press shortcut (nnoremap <silent> <leader>n :NnnExplorer %:p:h<CR>) to open NNNExploerer 2) wander around and press Enter to open a file in "edit window" and focus 3) edit file 4) press shortcut again to search for another file.

At 4) NNNExplorer closes (toggles). Can I prevent this? I.e. Use the same shortcut to either open or focus on the existing NNNExplorer window? I have a dedicated shortcut to close (terminal) windows.

Thank you for all the work and sorry if this has been discussed elsewhere. I only found hints about toggling so far.
