I'd like to be able to duplicate a single column in a table, or even copy it (with all its attributes) and then paste in another table. I have complex-defined columns (name, datatype,Description, other attributes) and I need to duplicate these attribute sets many times, in the same table (obviously changing the field name) or in different tables...

Very nice to have...

It could be useful to show, in tables, the fields which have been inserted in any index (beyond the PK). A bullet, or simply a specific letter, could points out the item/fields involved in one or more indexes.

This info helps the db designer in maintenance and overall checks of tables, or even entire database

Does Vertabelo still (eval'd early 2016) not infer joins based off the same column name? In data warhousing environments indexes are usually not defined in the DB and handled in the ETL app layer for performance reasons. This is the key feature I need from a modeling tool so you can simple reverse-engineer without manually defining every join relationship.

If I need to change a substring in many objects at once (ie change all "xxx" occurrences in "yy_z") it seems now I can do so only looking field by field in all my tables. I'd like to have a "search/Replace" feature which allows me to change strings or substrings in all my object names (tables, fields, indexes, ...) ....

Could  I hope so in the future?

I often need to insert the same set of fields in my tables. While I have only a single "fields set" to replicate, then I use a table template where I start from, but when I need to insert two different "fields sets" in the same table (not always the same) I have some problem. 
I'd like to be able to define objects like like "copybooks" or "includes" (containing fields definitions) to be picked up and then inserted in my tables. These "objects" could stay in a sot of "custom library"

Nice to have...

Since printing is not available in certain accounts, my goal is to export a PNG and print that instead. Following the instructions for allowing the PNG export to work properly does not resolve the problem.

When I try to get the png file from my DB design on Vertabelo dashboard, the process time is too long and I can not get it.

Please help me.

Export to PNG feature doesn't work any more:

I would like to see the version of the model in the model itself.

A solution can be something like a variable in a note or a new item version-stamp i can place on the model.

And when implementing this a variable or item showing the timestamp of last modification would be nice too.
