I am reviewing bank transactions. The columns are so wide they go way off screen. i am tired of dragging them one by one. What to do?

It can be really tiring to resize the columns one by one, Gerrit1. 

If you are referring to the column itself wherein other information won't show up on the screen and the column needs to be drag, you can manually adjust them at once to fit their content and be able to see the information. I've added this for you where the Bank Detail column has already been adjusted:

Another way around is to click the actual transaction so you'll be able see all the Bank Detail information. See the attached screenshot below:

Now that you already have the idea on how to simplify the process, you should be able to see the information quickly. Let me know if you need further assistance or have additional concerns when adjusting the column. I'm always around to help. Have a nice day!
