invisibliX 2.5 COULD be my favorite app for quickly and easily toggling the Finder's 'Show Hidden Files in the Finder' preference, and THANKS to its developers for making it free! However, it has some MAJOR PROBLEMS that make it too annoying to use until it's fixed:
1) When I click on the invisibliX menubar icon on my 13" MacBook, the drop-down menu drops down as expected. But, after I've made my selection from it, the drop-down menu DOES NOT DISAPPEAR as it should! And because some applications have lots of menubar items that force out other left-of-center icons, in order to make invisibliX's stuck drop-down menu go away I must first switch to the Finder to make the invisibliX menubar icon reappear, and only then can I click on it to make its drop-down menu go away! This is a MAJOR PROBLEM, and I'm amazed that no one has yet commented about it here. It also happens on my 20" iMac, so it can't be a machine-specific issue or a problem that only affects small displays.
2) invisibliX's icon is the least important item in my 13" MacBook's menubar, so I want it to display as far to the left as possible in case some other app's menus force my left-most menubar icons out. Around half of the times that I enable the invisiblix menubar icon in its Preferences and then quit invisibliX, its menubar icon disappears! I have to go through the process one or two more times just to get the its menubar icon to stick! This also is a major problem, especially since its menubar icon never shows up in the same location after restarting my Mac -- sometimes it displays on the far left, and sometimes in the middle -- so I have to disable and then re-enable its icon at least once just to get it to display on the far left side of the menubar.
There's at least one other problem with this version, but I can't remember it just now. And since I'm also sending this info to invisibliX's devs, they'll have their hands full for awhile anyway.
