"v4.0" ToDo, finally merging Victor's latest work

[ImprovedTube]

• [ ] Need to finish moving code from version 3.965.zip ( = view repo at october7 2022 ).

Need to review the lines of code missing from there. Almost none was useless. (The reason is, that Victor wasn't done moving it to 4.0 when he left. ( (3.945 & 3.1001 are somewhere inbetween with MF3. might have some fix/es.) )

• Background.js v4.0:

( Manifest3 is required for all Chrome extenison updates starting 2023 codeforcharity/MFv3 )

• [ ] chrome.tabs.sendMessage Solution? : groups.google.com/a/chromium.org/g/chromium-extensions/c/st_Nh7j3908/m/1muOgSX5AwAJ ( +general documentation😆 )

• [ ] reviewing the second half of background.js https://github.com/code-for-charity/ImprovedTube-for-YouTube/blob/35e7e45760e8f7cc260b0c7e9e9da2f414508a0b/background.js#L96

2. GUI BUGs

• [ ] old: #1174

new:

• [ ] https://github.com/code-for-charity/satus/issues/3
• [ ] https://github.com/code-for-charity/satus/issues/6
  • maybe also compare crxcavator.io/improvedtube/3.1001/satus.js (undocumented) ( Our "SATUS" GUI is incomplete not migrated completely)

---

• [ ] & "found a bug" & website bottom (can be migrated from our v2.0 or v3.2 )
  • [x] added a github-frame
• [x] #1171 Search also isnt complete (never was) & only finds single english words
• [x] "reset youtube cookie" does not appear in our options
• [x] Ads (blocking) shouldnt appear in the bottom only (unless it needs a fix) ( 3.1001 got the old(reasoned) order of features still. not sure the change is on purpose)
• [ ] #1803 BUG: menu/index.js fails loading sometimes (because code is split?) )
  • [x] might be fixed #2160

---

• (..and the code is split into several files for "easy editing" (contributors who do little) without building/concatenating). Maybe we should merge some again
  • [ ] research/benchmark if concatenating our code will save the users any significant IO? [on fragmented storage] or not
    • [ ] if so, updating build.py ( like it was 2 years ago: https://github.com/code-for-charity/ImprovedTube-for-YouTube/tree/HEAD@%7B2020-12-06%7D )
