Standard Window + simple Workflow: Locking Support, "open file dialogue" and stash Capability

Hi guys!

Wanted to congratulate You on the simplified views for 22.1!

As someone who is responsible for supporting users of varying git-knowledge, it is greatly appreciated that You are taking steps towards making Git more accessible to the uninitiated. ;)

(I for one would be very glad to get rid of our tertiary, error prone Git GUI, that we use for training purposes primarily, and which has striking resemblance to this new view ;))

Some Remarks from my side:

Our document-engineers needn't concern themselves with advanced git stuff, but would like to see:

* Ability to lock and unlock office files

* Open files from within GUI

* When they realize they forgot to lock, they should have the ability to stash changes before pull

Within standard view + simple workflow, these are not possible currently.

As a bonus, it would be nice for them to see the locking status of documents before attempting to lock.

Currently, You have to configure pull operation to fetch lock status. This is not something that the average user expects.

BR, Sascha
