Hi @christiansakai, sorry to hear about the trouble. I believe the issue is that VTR “remembers” the last runner you used. You should be able to work around this by explicitly stating the runner you want to use, or lack there of:
nnoremap <leader>nr :VtrOpenRunner {'orientation': 'h', 'percentage': 50, 'cmd': 'node'}<cr>
nnoremap <leader>or :VtrOpenRunner {'orientation': 'v', 'percentage': 30, 'cmd': ''}<cr>
Note You’ll want to modify the orientation and percentage arguments to your desired values (or remove them to use the defaults).
