I'm really, really having a hard time having the JavaScript environment be usable. If I go into anything with JavaScript I get the task "Synchronizing script resources with Tern server" that never has any progress and spawns a node process that takes as much CPU as possible. JavaScript has never worked well in MyEclipse (https://www.myeclipseide.com/index.php?name=PNphpBB2&file=viewtopic&t=27153&highlight= is still not fixed after 4 years) so just get out of the way and let me edit.

What does this mean
An internal error occurred during: "Registration".
Invalid thread access

When you are working in a JSP, for any element you are offered the universe of possible attributes. Wouldn't it be nice if you had MyEclipse notice which element you were actually adding an attribute to and have it limit to the actual set of valid attributes for that element?

I change workspaces a lot but I'd like to carry over my 'perspective' from one workspace to another, and in a seamless fashion too.

Make a new Perspective just for the various NoSQL databases. You have a database viewer for relational dbs. For example, for Cassandra you would have help for all the various sub libraries such as Thrift, Astyanax and all the other flavors.

It is not possible in the current MyEclipse Blue version 12.0.0.0 to remotely deploy, source level debug, or stop and start a network instance of a GlassFish 4 service, (like you can with WebSphere) and we would very much like to see this added as a feature set.

MyEclipse JSP editor does not highlight matching variables

control shift S should save all items, it does save all items but then it jumps to another source code tab. Highly annoying

Configuring a Maven project via POM, project properties, preferences, archetype XM in metadataL, etc. gets very difficult to match to an already extant Maven project. A good, usable and complete Maven project settings which includes lifecycle mappings would help a lot.

edit and refact js better

Whenever you set your project to a certain version of a facet, MyEclipse should be able to allow you to change the version. Example. (Changing from JSF 2.0 to 2.2 facet.)

It should give you all the problems your project may have after you change so you can upgrade projects quickly.

format html/jsp/js better

The .metadata folder for a moderately sized maven projects can reach almost 2GB, probably more for large projects. On a PC with a SSD and limited HDD Space that is outragous. It would be nice if that folder could be made smaller (Also a UI option to cleanup the cached files could be helpful.)

A common painful task is creating multiple named instances of the same server. I just did this for MyEclipse 2014 where I needed a WebTier instance of Tomcat and a MidTier instance, each listening on their own ports. The current MyEclipse plugin does not support this but it can be done through the Run Configuration. Actually, once I figured it out it was not to difficult but I'm sure I will have forgotten it by the time I upgrade to the next release

Round-trip Java / UML techniques are quite useful in agile projects, and basic Java beans generally work quite well - but as soon as we start using Java annotations, things get dropped / missed / messed up and must be reconciled manually.

Although the list of running threads within a Remote Java Application in the Debug panel is great, it would be nice to allow for easier labeling of the threads from within code, memory utilization and overall better visualization in real time.
