Where is the "Zotero-Addons"?? Is this another plugin??

If it's good & convenient enough, why hasn't it been mentioned or linked in https://www.zotero.org/support/plugins ??

Updating Zutilo for Zotero v7 is apparently still underway.

For anyone else about to migrate to Zotero v7, it is important to first check your plugins for v7 compatibility ...

OK. Now I think I need to temporarily revert back to Zotero v6.

Since I use the portable version https://portableapps.com/apps/office/zotero-portable (release history: https://sourceforge.net/projects/portableapps/files/Zotero Portable/ and dev history https://github.com/pedrom34/ZoteroPortable-dev-repo/releases), I can easily overwrite the app files of v7 by those of v6, without touching or affecting any of the data such database files *.sqlite and preferences, thanks to PortableApps.com's portablization mechanism that separates app files from data files.

However, after reverting back to v6 in this way, and if I launch it, will it mess up the database files such as zotero.sqlite, or mess up the settings/preferences? Or in other words, has Zotero v7 changed the database's architecture/format/layout/etc., such that after upgrading to Zotero 7, the database itself also gets upgraded and is no longer compatible with Zotero v6?

@dstillman: thanks for your confirmation. I had reverted back to Zotero v6, but even after this, most addons/plugins are still disabled:

But all of them are enabled and working properly before I upgrade to Zotero v7. That's very strange. How can I at least temporarily enable all addons/plugins?

@northword: will that make me lose any plugin's settings/preferences (accessing them is the whole point of temporarily reverting back to Zotero 6)?

so another round of playing catch up to make zotero usable.
