When you take a look at an environment for an app in the Mendix Cloud Portal, there is a "View Recent Logs" button. When you click on it, it opens the logs in a pop-up window. The window is so narrow however, that it's impossible to read anything (the prefix for every entry already takes up most of the width). The horizontal scroll bar also isn't fixed to the bottom of the pop-up - you have to scroll all the way down to find it. My first instinct was just to copy everything to a text editor to read it, but ctrl+a selects all the text on the entire page behind the pop-up, too.
My idea would be to make the pop-up much wider, so I might be able to read some logs in the window directly. And additionally, it would make sense to add a "Copy to Clipboard" button, that automatically copies the whole log text, and doesn't make me manually select everything to paste it into a text editor.
