you are allowed to exit and enter Malaysia as often as you want, you just cannot enter Thailand during the application process. I received this information on email from the embassy because I was considering going to Singapore for a few days if the application took too long.
I went to Malaysia (KL) to apply for non-o dependent visa. I uploaded all my documents whilst in Thailand and saved my application. Arrived on the Monday afternoon (was a public holiday), uploaded my entry stamp and submitted the application. I received my evisa on the Friday at around 18h00. They requested me to upload all my passport pages, and additional documentation relating to my husband's business registration, but other than that a seamless process.
Much more to do in Malaysia, cheaper flights, and in most cases don't need a visa to enter.
Having just had a surgery, I updated my will to state that my organs be donated and my body also be donated to a university for research or whatever other reason.
Just check with a lawyer regarding the laws of a valid will.
