so that no two records can have the same value for that field or fields. This is usual in relational databases, but seems to be missing in Memento. It is also very important for large libraries, where one might enter the same information multiple times by mistake.

例えば、私が使う例として、GoogleSpreadSheetsにデータシートが出来ています。複数行のデータです。
これを例に、ライブラリを作成する例。Mementoクラウドへのアップロードのタイミング。ライブラリとクラウドの各同期のタイミングなどが、理解できません。
豊富な機能をご自慢したいのはわかりますが、それも基本を理解していなければ、ユーザーは、快く利用でないのではないでしょうか。
私の場合は、翻訳しながらなんとか一つ、二つのライブラリを作って利用しておりますが、次に新しいライブラリが上手にできる自信がありません。
それは、あまりにも偶然にmementoDBが出来てしまうからです。
また、一つのライブラリをもう一台のスマホで使い場合の例題も上げて頂きたいです。よろしくお願いいたします。

User/Group permissions.
Disable selective functionality on the Side Menu so that as example Import and Export functionality is not possible for specific Users/Groups on a Team Subscription
Basically more granular access control for Users on the Side Menu

I like person i will give for us. And contrary oke

Seria muito útil que os campos de valores tivessem uma opção para memorizar um novo valor como valor padrão

Add a field to chose and change units for numerical fields on entering data rather than only upon editing database structure and design

It's wonderful that we have a round function when using the calculation field.
However it would be better if we could get a round down or round up function. So that 4.4 becomes 4 with round down and 5 with round up.

In addition, a decimal function would also be handy with all round functions. so that 4.68245 becomes 4.7 with round 1 decimal.

Add Customizable PDF export option for mobile app. Its very urgent for sending report card to someonr

Changining background color for entrys

I am trying to add warranty periods and the duration option only allows for up to days to be entered. Request that it be extended to allow for duration of years instead of just days

In groups view (accordion), when one group is open then other will be closed

Add contact from a different Google account
Ability to search contact using Labels (if there are 500 contacts it takes a lot of time scrolling down to find the contact)

C'mon! How could this have not been implemented yet?
It would be awesome to use the emojis as icons to the libraries and any other place you can add icons.

When sorting entries by a Single Choice field, it needs to be the same sort order as manually done in the Items list editor (so you can manually change the sort from the Items list)

Khi xuất dữ liệu ra dạng excell , không thể hiển thị đúng tiếng việt, không tìm được font tương thích

Allow users to control visibility of fields through scripting. This would be useful for situations where extra data is needed/not needed, depending on user input.

I do some heavy work writing scripts for my employer, having a way to backup the scripts/structure to a 3rd party would be excellent. Also it'd get my github stats up :)

Our business makes heavy use of action scripts. One pain point is that we can't link from the arguments pop-up and have less control over those fields than we do with library/entry fields.

Allow groups to be devided into subgroups. Could be displayed as a collapsible / expandable tree view. Would really help me better organize a big and very complex database
