Version 2.6 of package Ioccur has just been released in GNU ELPA. You can now find it in M-x list-packages RET.
Ioccur describes itself as: ================= Incremental occur ================= More at https://elpa.gnu.org/packages/ioccur.html ## Summary: This package provides the command M-x ioccur, which is similar to M-x occur, except that it is incremental. You can jump and quit to an occurrence, or jump and save the search buffer (ioccur-buffer) for further use. You can toggle literal and regexp searching while running. It is auto documented both in mode-line and tooltip. It has its own history, `ioccur-history', which is a real ring. To save `ioccur-history' via the Desktop package, add this to your init file (see (info "(emacs) Saving Emacs Sessions") for details): ## Recent NEWS: [Not provided 🙁]
