4 | * Possible future work: |
5dd44dce |
5 | * |
b921687e |
6 | * - configurable choice of how to allocate node names? |
7 | * + possibly a template-like approach, choosing node names to |
8 | * be the full section title or perhaps the internal keyword? |
9 | * + neither of those seems quite right. Perhaps instead a |
10 | * Windows Help-like mechanism, where a magic config |
11 | * directive allows user choice of name for every node. |
12 | * + Only trouble with that is, now what happens to the section |
13 | * numbers? Do they become completely vestigial and just sit |
14 | * in the title text of each node? Or do we keep them in the |
15 | * menus somehow? I think people might occasionally want to |
16 | * go to a section by number, if only because all the _other_ |
17 | * formats of the same document will reference the numbers |
18 | * all the time. So our menu lines could look like one of |
19 | * these: |
20 | * * Nodename: Section 1.2. Title of section. |
21 | * * Section 1.2: Nodename. Title of section. |
5dd44dce |
22 | * |
b921687e |
23 | * - might be helpful to diagnose duplicate node names! |
