Top-3 most annoying things

[neSpecc]

Hey there! We're introducing the new discussion format:

Write a short list of the most annoying things or bugs in editor at the moment. It will help us prioritising further improvements.

Please, be short and stay in a following format:

N. Short description (Link to a corresponded Issue)

Do not write about feature requests. Here is a separate discussion for them.

Example

1. New block insertion on inline-pasting (Paste: new block is created instead of inline-pasting #2142)
2. Cross-Block selection breaks ([Bug] Cross block selection selected state gets wrong when pointer moves out edit area #2167)
3. Lack of types for Tools (❓module declaration error. #2143)

1. Markdown support (Markdown support?  #709)
2. Lack of types for Tools (❓module declaration error. #2143)
3. A filter like Notion, because in current filter, it gets out of position if searched.

1. Hide toolbar actions for 1 field. later I need to allow a maximum number of blocks. Then sometimes I have to show it and sometimes I don't. Now I do:

.ce-toolbar__actions--opened {
    display: none;
}

1. Lack of updates/maintenance for blocks built by the EditorJs team. I see these as being part and parcel of EditorJs, and I wish they were updated and maintained.
