Hi Vikram,
While the nested tags are an improvement...
a) they're not user-friendly (users have to learn the use-a-colon trick from somewhere)
b) the bigger issue (to me anyway, but I get the impression it's big for everyone) is that when adding tags to an Item, there's no auto-complete
As I've mentioned previously, if you have a tag called "Utilities" you have to type the whole thing every time. And because you can't scroll through the sidebar (categories, tags, etc.) when in edit mode, it's impossible to see the names of your exiting tags while trying to type them in. So it's really easy to accidentally end up with multiple tags that were meant to be the same thing: "Utilities" and "Utility" (because you didn't remember your original tag was plural, not singular) and "Utlities"(because you made a typo).
This is only compounded by the nested tags "improvement": Did I call that nested tag "Utilities:Power" or "Utilities:Electric"? Without being able to scroll the sidebar — and more importantly, without auto-complete options — the only thing one can do is save the Item, then drag it to the correct tag in the sidebar, which is an extra step that shouldn't be necessary.
On top of that, there are two more problems that compound the issue:
1) It's not possible to drag any item that isn't active (highlighted in blue), so there's an extra click involved (not a big deal, but I know this isn't normal behavior because I've never had this problem in any other app)
2) When you do drag the Item to the sidebar, it's not being put in the Tag that you're pointing to with your cursor, but rather the one below it:
Of these problems — all of which need fixing, and most of which I feel shouldn't have made it out of beta — in my view the auto-complete is the most important (and unfortunately probably the most work for your team). If I'm adding a tag and type "Uti" and Enpass offers the auto-complete option "Utilities" because that tag already exists — that's saves a lot of hassle.
But as I say, all of these are important, and many of them are due to the fact that the UI has been redesigned to work across a bunch of platforms, instead of having a Mac-like app for the Mac, an Android-like app for Android, etc. In Enpass 5 (for Mac anyway), editing an Item took place in a child window, and it was possible to scroll the sidebar in the parent window behind it. But in the new design, opening Edit makes it impossible to do anything else in the app. It's not even possible to open the preferences when in Edit mode.
Having been part of UI/UX teams, I definitely understand the instinct to try to make one UI that works everywhere. It's a tremendous time-saver and makes both the design and QA processes much easier. But when it makes the app user-unfriendly, you end up shooting yourself in the foot.
I'm a big proponent of Enpass, which is why I'm so active in these forums, and why you'll see me both criticizing and defending. But I don't recommend Enpass to anyone else at this point because compound issues like this make it difficult to use — and I run into issues like this every day.
