So far in this thread, you have been reading the opinions of 2 of the 156,000 members here, but until some of the 156,000-2 decide to join in...
Point 1: The sections (and sub-sections) of the existing index pages may be directly addressed, as in:
Point 2: Suppose that GM's suggested "Master Index" is put on a Wiki page with generous use of sections and sub-sections.
Change 1: Convert this thread title into a re-direct to GM's "Master Index"
Point 3: Presume the O.P. of a thread starter has prefixed the thread with the "most significant" of multiple possible tags.
Change 2: Make the prefix (category) tags "click-through" to the associated section of the GM "master index".
A "Master Index" section tree might look like this (for prefix Hardware):
. . .
MI:Hardware:K1:Serial Port (this is still a directly addressable (sub-)section link into the existing index pages).
MI:Hardware:K3:Reading Light (does not exist at the moment)
. . .
I think the Wiki supports five (or six) header levels, that should get the browsing visitor fairly close to what they want to find with only two clicks. (prefix, MI:index link) or (This title, MI:index link).
I have re-formatted a lot of Tools and Hardware to match our newly suggested index entry style guidelines (and added those to all index page introductions).
Comments from the 156,000-2 not yet heard from are welcome here.
A bit of Wiki index editing from the 156,000-5 not yet contributing to this effort would also be welcome. Go ahead, whatever you add can't be less than what we have and "Management by Exception" is not a policy here.
