request for few feature

[cyberpunk-edgerunner]

currently if I want to make a rectangle annotation, I have to either click to 'create Rectangle' button for use the shortcut 'control+R'.
and if I want to edit an image there is no choice but to click on the edit button.
My people in my company uses labelme and I want to request the below given feature, the top 2 are most request:

1. The 'E' key press should act like a shortcut for the edit button
2. ubstead of pressing "control+R" for the edit, it would be better to press just 'R' for the rectangle mode.
3. if possible add a feature to delete or, or move an image to separate folder (add a move/delete button)
4. default lablel - many times we annotate only one object in those cases it would be very helpful if one can set the default label so that the number of clicks are decreased thus increasing the speed of annotation.

Thank you in advance to Kentaro and Mujin Inc, the labelme is a wonderful offline tool. I have great respect for you and your team. If possible I would be very glad to work with you (in fact I am looking for a new job - I have experience in AI/ML Engineer, Data Analytics, Design and little bit of IOT. P.S. I am learning japanese on duolingo app)
and of course thank you for your quick responses.
