Alright everyone!
I have just released v1.3.0 of this hack, and I have given you what you asked for: the ability to have the Who Viewed information displayed in a Pop Up, instead of directly in the ShowThread page.
I made it so that you can choose which Display Mode you prefer - to have the Who Viewed information show up directly on the ShowThread page (as it was for all prior versions), or to only show a Link on the ShowThread page that opens a Pop Up Window with the Who Viewed information there.
I also consolidated and cleaned up the code - so now (among other changes) there is a distinct Configuration Section in the ShowThread.php code addition.
For users upgrading from v1.2.6 (and these instructions ONLY apply to users coming from v1.2.6), download the v1.3.0 instructions and do the following:
1. Remove the code addition you previously had added to Misc.php. It is no longer needed.
2. Follow Steps 3-4 in the v1.3.0 Instructions file.
3. Replace the old (v1.2.6) code additions to ShowThread.php with the new version of code (Steps 5-6).
4. Replace the old (v1.2.6) code additions to the SHOWTHREAD Template with the new version of code (Steps 8-9).
5. Follow Steps 10-11 in the v1.3.0 Instructions file.
6. Test to make sure the hack works properly (do this BEFORE you change anything in the Configuration Section).
7. Optional: Edit the Configuration Section in the new Code you just added.
That's it!
Let me know what you think of the new Pop Up functionality!
