Please add a back button. This is the second time this semester that I have went to delete an unwanted row in a table/ a single highlighted word and that the key controls on lab flow will delete the whole table. As a tool to input data and experiment results, having the option to reverse unwanted changes should have be implemented at the conception of this website.
This isn't an idea as must as it's absolutely necessary to the function of website/program that is used to record data. The fact that the programmers didn't put this into the website in the first place is absolutely appalling and idiotic.
