my vote is to bump the ODB size limit to 1999*1000*1000 (not quite 2GB). but this needs to be tested. especially save and restore from ODB, XML and JSON
files, including how long it takes to save and load a 1.9GB ODB. K.O. |

At the run start mlogger writes the ODB to the .mid file. This needs conversion (binary ODB -> XML ASCII) which can take time.

It would be nice to have MIDAS notifications pop up outside of the browser window.
To get enable this myself, I hijacked the speech synthesis and I added the following to mhttpd_speak_now(text) inside mhttpd.js:

When trying to select a run script on an iPad or other mobile device, you cannot enter subdirectories. This is caused by the following part:

There are certainly dozens of people who do "I don't like pop-up windows all the time". So this has to come with a switch in the config page to turn it |

people using Edge/Chrome/Safari/Opera saying "it's not working on my specific browser on version x.y.z". So I'm only willing to add that feature if we
are sure it's a standard things working in most environments.

Ok, I implemented desktop notifications. In the MIDAS config page, you can now enable browser notifications for the different types of messages. Not sure
this works perfectly, but a staring point. So please let me know if there is any issue.

correction: ODB shared memory is saved to .ODB.SHM each time a client stops, this is db_close_database().

The original design of the midas shared memory (back in the 1990's) was that the ODB shared memory file gets
