I have a hard time finding a freeware program where you can joiner images together in nonlinear strip.

Supposedly I have images a,b,c,d,e,f.

I wish to orientate them where I can specify the columns and rows like 2 by 2 or 3 by 2.

ex.

a,b
c,d

or

a,b,c
d,e,f

I'm looking a stop watch program that can keep track of multiple times.
I tried MultiTimer but this program lacks the hotkeys to effectively stop and start each timer.
If someone can create a program similar to Multitimer but with hotkeys then I will like to
assign 1 through 0 to toggle each timer to start and pause and resume if pressed.
ctrl 1 through 0 will clear the each timer's elapsed time.

I am accustom to use this autohotkey script which allows me to paste the last 5 history items on the clipboard. The problem with this is that you would have to cycle through the list  to get to the items in the history and a key combination is required to be held down for operation. I was hoping someone would be able to add or modify upon this script to make it easier to use.

The features which I request are the following:
Maintain the feature of having the last 5 entries in the list
Able to allow for mouse to to double click any of the entries for pasting
when the mouse goes on any of the 5 entries:
         the hotkey is no longer needed to be held down and only a click elsewhere away from the entries is needed to get out of the clipboard entries view.
         a range of entries is selectable for pasting when the shift key is held down and mouse is clicked on any two of the five entries
