A while ago, I posted my list of protips for browsing saidit, I suggest everyone check it out if you haven't already: https://www.saidit.net/s/SaidIt/comments/4v80/pro_tips_for_browsing_saidit/
Well now that you've seen those, here's some more super unknown protips that can make your saidit experience even better:
This is a stealth feature but incredibly powerful. You can upload something to imgur, and get the direct url to the image, in 1 click through saidit. Just go to the "Submit a new link" link on the front page (even if you're not going to post) and then below the url box, there is a "Browse..." button to upload things. Drag-and-drop any image file from your desktop to this "Browse..." button on saidit, and it will automatically upload it to imgur, and spit out the URL for that new image in the URL bar. It might be one of the easiest way to upload images on the internet and get the url quickly.
If you see a post or comment that says for example "posted 1 month ago", you can hover over that with your mouse and it will tell you the exact date and time that post was posted. And for asterisks that show edits, you can hover over the asterisk and see how long ago the edit was made!
If you want to create a "multisub" you can do so by going to any sub, and hovering over the subscribe button (but not clicking it) and you will see a "multisub" dialog box pop up. Here you can enter other subs and create multisubs that will save to you user account, so you can browse them later.
Also you can manually create a multisub right in the URL, by combining subs in the URL with plus signs like this: saidit.net/s/music+comedymusic+musicvideos
