How to move a pasted item to the top of the history
Turn on Move pasted item to the top in Clip by Zaweba's Settings, and whatever you paste from the history jumps back to the top of the list.

In Clip by Zaweba, turn on the Move pasted item to the top setting. With it on, any item you paste from your history moves back to the top of the list, so the things you're actually using stay close at hand. With it off, items keep their place based on when they were copied.
It's a small switch, but it changes how the list feels, so it's worth understanding both ways.
Finding the setting
Open the main window from the tray menu with Open Clip and go to Settings. Alongside the hotkey, the history limits and the choices about what to record, you'll find Move pasted item to the top. Turn it on, and it applies from your next paste.
How the list is ordered
It helps to know how the popup arranges things. Press Ctrl+Shift+V and you see pins first, in the order you pinned them, then everything else newest first. Every row is numbered, and Ctrl+1 to Ctrl+9 paste rows 1 to 9 directly.
Copying something that's already in your history moves it to the top instead of adding a duplicate. That happens whatever the setting.
What the setting adds is the same treatment for pasting. Normally, pasting an older item from the list leaves it where it was. With Move pasted item to the top on, the item you paste becomes the newest, as if you'd just copied it.
Who it suits
Turn it on if you work in bursts with a handful of items. Say you're filling in a form with details from an email: a name, an order number, an address. You paste each one several times over the next few minutes. With the setting on, all of them stay near the top, within reach of Ctrl+1 to Ctrl+9, rather than drifting down as you copy other things.
Leave it off if you like the list to be a strict record of when you copied things, or if you often use the row numbers by memory. With the setting on, numbers change as items move, so the thing that was #12 a moment ago may now be #1.
Pins are different
Pinned items aren't affected. They always stay at the top, in the order you pinned them, and no history limit ever removes them. If something should always be one key away, such as your address or email signature, pin it with Ctrl+P in the popup or Pin in the main window, rather than relying on it staying near the top.
How it interacts with limits
Clip keeps 500 unpinned items by default, adjustable from 10 to 100,000 in Settings, and the oldest unpinned items go first. With Move pasted item to the top on, items you use often keep being refreshed, so they're less likely to be trimmed. It's a gentle way of keeping the useful things around without pinning everything.
Finding items either way
Whatever the order, you can always find something by typing in the popup, where every word must match the text or the program name, or by jumping straight to a number with #, such as #37. The ordering just decides what's under your fingers before you start typing.
Try it on for a day. If the items you need keep being at the top, leave it on. If the shifting numbers bother you, turn it off again in Clip by Zaweba's Settings.
