Basic html links will open in Opera as long as it's the Default. But I wanted many other sorts of links to open in Opera. For instance a Twitter post of a YouTube link. Android prevents this, on purpose or not.
Enter this Android app "open link with" - with this installed, the link will still open in the YouTube app But the YouTube Share selector under the 3 dots will now include opening in Opera. No ads, and various other Opera advantages.
Well I have some further thoughts on this Email Migration conundrum and can say what my conclusions are.
The bottom line is that I am staying with Fastmail for a while and may well make that long term.
I set up a new Account on Fastmail which is of the type email@example.com (other countries are available) and that is working well. In the main I use as email just the now-alias identity firstname.lastname@example.org which Fastmail set up for you which is very easy to use and puts emails directly in your new Fastmail account. The Fastmail help people were great, even with my blundering.
At first I thought I would try out the process of migration to another account, transferring the emails as I went along, using my Gmail account as the target and copying emails out to there. It was a disaster because I was approaching it from a piecemeal viewpoint and saw myself collapsing in a welter of lost and/or duplicated emails.
So I decided to inform as priority those contacts whose emails I would like to know about first like Medical stuff, Banks, key shops and other financial things; in general those that I register with but do not normally write to but who send emails which MUST go to the right place.The rest can be worked through; for them operamail is still working, but they and even close friends can wait.
A necessary trick is to have a good checksheet and keep count. Memory only lasts to the next email.
I've taken the opportunity to reduce my inbox to manageable levels (Over 2000 to less than 10) and tidy up my folder logic. In this I was lucky to discover the Fastmail App (Which is very good indeed) so that I could sort out a lot of that while watching the latest version of my Netflix serial in the comfort of my sofa and a glass of wine
If I do decide to change to a different Email service I now know that a lot of the transfer work can be done very easily and the experience I'm getting in informing contacts will be invaluable.
But I've bought myself time to take that decision, and I have to say that Fastmail is actually rather good.
