## Wishes to all web frameworks

- Documentation about how to upgrade, all required steps. Or alternatively, a script that does changes required to upgrade.
- Using parts of frameworks as separate packages, like:
  - Authentication, like OAuth2, Gmail, etc
- Option to not use websockets, because at some corporate networks do not allow them.
- Option to not have Javascript at frontend, having SSR only. Working with and without Javascript at frontend, like ufront did.

  - https://stackoverflow.com/questions/65547266/how-to-store-my-session-mysql-with-express-mysql-session
- Not having build step:
  - Keep all files at directories they currently are, with understandable directory structure naming, like:
    - Feature name
      - Feature part name 1
      - Feature part name 2
  - Only use file from it's location on page where it is needed
  - Cache dependencies. Make possible coding offline.
  - Do not uglify

  - I merged all branches to one main branch, because merging between branches did take a lot of time.
  - Do not use linters like eslint and prettier. What I did, is I removed all linters, like eslint, prettier etc, because they did disagree about syntax. Point is to make to code minimal change, that fixes something, or adds some feature. Not that most commits would be about fixing syntax.

### Group and count by first character of board names

From https://github.com/wekan/wekan/issues/4578#issuecomment-1250143726

When there is a lot of boards, it is very useful to group by first character of board (and after that click charater to see list of boards for that character, to be added later). I could not figure out how to do it with MongoDB aggregate query. Here is how I did it with SQLite, for type board. SQLite returns results immediately. Note that emojis, UTF-8 shows also on Netsurf browser. TODO is to figure out, could I get these visible also in FreeDOS Dillo browser.
```
SELECT _id, substr(title,1,1), COUNT(*), type from boards
WHERE type=:type GROUP BY substr(title,1,1) ORDER BY substr(title,1,1) ASC;
```
Actually, somewhere I saved answer from ChatGPT or Bing AI search, what this SQL query using MongoDB Javascript syntax. So maybe I should ask again.
