Good afternoon.
Okay, I agree that the “save” option can be questionable. 
But think this way: if you make an edition and after saving TB shows a point that can be deleted, will you delete it or leave it?
Also: if you make an edition and after saving TB says that a segment can be simplified, will you simplify or leave it that way!?
Again: for loops … will you fix it or leave it?
On my normal editions I found myself putting everything okay (fine and shine) and, before saving, I click on each of those 3 buttons in order to “clean any mess” that can be cleaned (mainly those suppress unneeded junctions and suppress unneeded geometry buttons). Only after I make a save. I’m not talking of editions in zoom 2, 1 or 0. I’m talking of editions on a bigger zoom – mainly when adjusting segments to satellite image, creating new small roads … After such type of editions, it is normal to have to make some cleaning … and for me, those 3 buttons are almost like … say … CCleaner: it cleans some “garbage” that you left behind.
In the end, such functionality could be only available on a bigger zoom.
The idea is to optimize a repetitive action, and honestly, I do not see any problem on applying these 3 functionalities before a standard save.
The suggestion to include a “save” would be almost like a replacement of the standard save button: if you click on the standard save button you know that you want to save, right!? So, if you will click on the new suggested save button you also know what you want to do.
The suggestion was to make a save button, that intends to be a “normal” save, but immediately before saving it would clean all the “garbage" that such 3 functionalities allow cleaning!
But, again, if you see that a save can be problematic, forget the save suggestion.
It is just an idea… not a demand. 
Thanks for your time and your great work with this tool
