@fpy asked me that I could revive the development of AltSearch Adding HTML code to ODT manuscript - #4 by fpy, but it is not so easy for me.
Can you write here the bugs in AltSearch and your ideas to improve it? To see the extent and interest. Unfortunately probably it will not be in my possibility to make some big changes, but it seems I could translate the comments to English to make the code accessible also for non-Czech speakers.
One bug: AltSearch Extension error
