feedly
In the Chrome version of Feedly, the left sidebar auto-hides. I've spent the last 25 minutes attempting to make it stay open permanently (like it does in all the screenshots of Feedly), but I cannot. So every time I want to see something, esepcially in a nested folder, I need to manually move your mouse and click several times.
There must be something I'm missing >.<
Yes!
In Preferences | General, find "Filter Empty Collections" and set it to "On".
Feedly changed this sometime before Aug 6, 2018. Now, you have to click the tag name in the left navigation bar, then click the three horizontal dots in the right pane where all of the tag options are, then select "Delete" from the context menu.
Wonky screenshot, but you can see the three dots over there on the right...

Maximize the width of your browser window.
I found your question when googling the same, and just found the answer on another site. Worked for me in Chrome, but I had to maximize it ALL the way, not just close.
