Microsoft added a feature that is so useful for B4X development.
The timeline (from task view).
Calling up the task view(the icon next to Cortana) will present you with a screen of tiles that represent what you have done recently (up to 30 days if you enable sync).
Entering .b4J in the search bar will call up all things related to b4j, it shows the name of the projects you were working on/looked at in the IDE.
Clicking on a tile will open the B4x IDE and load the project if it was a b4X file.
If the tile relates to a webpage it will open that.
Finally a feature I will use.
