What tool/software/website/add-on you use in your workflow or occasionally and you think more people should know about?
For me it’s those
very fun for trying out random glitch effects
for when you want to edit something quickly and don’t feel like opening GIMP
Image Vectorizer
One click export multiple resized images for all of the popular social media sites
i don’t know if photolemur is unpopular but it’s very useful for quick getting different looks, at least for me, because i don’t know how to color correct properly
http://quadspinner.com/gaea/
again, i don’t know if gaea is unpopular but it’s definitely not as known as world machine, vue etc
this site is very clean and minimal for making videos into gifs, speed up videos, crop videos and lot more useful stuff
collect, search and organize your image files, never used it but it looks cool/useful
Direct folders
Gives quick access to the folders you use the most.
From developer:
Access your folders from anywhere
Just double click on an empty area located on the Desktop, Explorer or File Open/Save dialog box to bring up a menu. Select a favorite or recent folder from this menu and the file dialog immediately jumps to that folder. If you activate this menu from the desktop or tray icon, this folder will be opened in Windows Explorer.
Now you can jump to any deeply nested folder in just a single mouse click! It also automatically resizes every standard file dialog, so that you can see a larger number of files. You will be able to find what you are looking for with a lot less scrolling.
I used to use Direct Folders, but the last update was released two years ago, while Quick Access Popup is still frequently updated, is fully freeware, and offers much more options. I can recommend it.
On the downside, like Direct Folders, Quick Access Popup also doesn’t work in Blender, because Blender has its own file IO system.

Still love their software though 
but joking aside
