My company is looking for replacements to the stock mail and calendar modules for Vtiger. I have demoed the Roundcube mail module from VGS and while I like parts of it, I am worried by its inability to connect emails to related records (an issue that also exists in the stock mail manager) as well as the generally slow speed the module functions at.
Likewise I have seen that Boru Apps has a calendar replacement, but I have not had a chance to demo it. Ultimately though my question is can anyone point me in the direction of other replacement modules?
We would also be open to the prospect of working with a developer to create new modules to replace the existing ones, at least that way we could be certain that all our requirements are met. Can anyone provide some help?
