This request is continuation of Feature request 2964441 (see https://sourceforge.net/tracker/?func=detail&aid=2964441&group_id=23067&atid=377411\).
Synchronization, the excellent phpMyAdmin's feature, has some lack of flexibility.
It just synchronizes one DB into another, but very frequenly the task is far more complex.
F.e., not all tables in source database must be transferred, or brute synchronization fails because of different source/target server versions, etc.
Suggestion is to let user fine-tune export & import parameters.
Let's add under listboxes "Server" & "Database" ("src_type", "src_db_sel", "trg_type" & "trg_db_sel") a new pair of listboxes with previously bookmarked Export & Import templates (see Feature request 2964441).
That will entirely automate the complex database deployment process. It is very needed!
The intermediate file (exported from source database) should be saved with unified name on phpMyAdmin's host machine.
Its name (and other details of this complex procedure) must be reported to user.
The further development of idea is to let user "bookmark" deployment parameters, i.e. store source/target servers & databases, and export/import templates.
