If you like to use Sticky Notes, do yourself a huge favour and stop using the Windows 10 Sticky Notes tool. Instead, go to Zhorn Software and download Stickies by Tom Revell. It works much better, has more features, is very well documented and is very intuitive. You can also download a Skinner Tool if you want to design your own interface, or you can use one of the many prebuilt skins (although I prefer the one that came with an older version which is attached here).
I've been using it for several years and I freaking love it.
To use the attached skin, save it to the
skins subfolder of the stickies install folder and rename it to
stickies8.ssk (Daniweb doesn't allow uploading of ssk files).
