Steps to Reproduce:
1 - Open Windows Explorer,
2 - Click on any location or folder in navigation pane (highlighted in picture) with Ctrl held-down or middle-mouse click,
Result - Folder opens in same window.
Expected result: selected folder would open in a new tab - behaviour similar to when Ctrl-clicking folders in main view of Windows Explorer.

Also I would like to ask for another feature if possible. Consider adding a keyboard/mouse shortcut option to opening folders without changing the view focus to newly opened folder but maintaining it in location where one selected said folder.
Also, one question that I am not sure if you can answer: is there an ETA for patch 1.19 of Groupy? I'm eagerly awaiting for seeing LibreOffice tabs fixed. 
All the best.
