You can copy directory path from explorer, paste it into open/save dialog and it'll navigate there. But your suggestion is much easier and intuitive to use.
Actually Explorer and open/save dialogs have some kind of recently used (or most used) directories. But they always contain some junk for me. Listing currently opened directories there could help without need to rework UI.
Dragging a folder from Finder into the safe file dialogue opens that folder in the dialogue.
You can also drag a search result from Spotlight in to the save file dialogue.
Also works with the open file dialogue.
MacBook touchpad right under the keyboard makes drag n drop feel like a superior method.
For context, I have a fairly extensive AutoHotKey script and a 22 button Razer Naga configured to automate repetitive tasks on my Windows 10 work PC, and Windows 10 has proven itself to be super stable and robust at work and home, so I’m by no means a bias MacOS fan or whatever, and if I’m honest I really do prefer Windows 10... and my 2013 MBPr died the other day, and there’s not much chance of me buying another MacBook any time soon because they’re over priced and lack ports.
Where was I going with this?
Oh yeah, there’s some things MacOS does that are great UI design....
And the good news is that, you can achieve that with Listary. I'm using an old version of it due to few years ago I found that new versions do perform as fast as the old ones.
It is possible to start any program via a file association even if it does nothing with the file that the action was activated on.
Saving a new file only requires the file chooser if the application was started first. If the file is created in Explorer via the New ... Templates and then opened the use of the file chooser can be avoided.
I have a dozen or so software shortcuts (notepad++, cmd, etc) in the SendTo folder, which works similarly.
(The SendTo folder had a similar wave of too many then too few applications installing to it. I feel like every application that really made sense on the context menu seem to have moved to direct context menu entries in the main context menu rather than SendTo.)
Rationale: Project are often contained in a single root folder. I often start by opening this folder in Explorer. Some programs can be started by double clicking files. Others cannot. Saving new files always requires interacting with the save dialog and thus browsing to the project folder again.
