I'm going to have to agree with most of the people here. The lack of being able to import into a folder structure is really important. Trying to import from lastpass and I've found the same as all the others. I took a look at the csv that lastpass exports. It clearly labels the folders in a "grouping" header. I'm a developer as well, so as others have stated, I know it takes time to tackle all these issues. I'll also echo @TheOnlyMerlin when I say in order to get people to switch, you need to make it easy for them. This is not easy. Thankfully I only have about 100 items, but I don't know if it's worth my time to manually add them to folders.
Another issue... I'm on Ubuntu 17.04 using a dark system them and a dark theme in firefox (v55). The enpass desktop app and firefox extension don't play very nice with the dark system theme. In the desktop app, I can't see the username because the text is white as well as the background. In the firefox extension, I have the same problem with the options in the dropdown on the bottom right of the overlay / popup / whatever-you-call-it.
I had one other strange problem. I deleted all the entries I had imported and tried to import the csv a second time. For whatever reason I got some kind of error saying it couldn't find a lastpass export (or something to that effect). I then copy and pasted the export (since lastpass opened it in my browser) into a csv in a different directory with a different name, and it worked just fine. It was very strange behavior.
So after all the negativity, I *would* like to say "Way to go guys". It's impressive how many platforms you guys are supporting. And thank you for supporting Chromebook (even though you're doing it via Android :-) ). The fundamentals of the application feel solid. I'm hoping you guys are working hot 'n heavy on this importing business. Feels like you're losing a fair amount of potential customers because of it, and I'm really hoping you succeed. You've got the start of a pretty good thing going.
